Can a central angle be obtuse?

What is a obtuse central angle?

An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.

Can a central angle be greater than 180?

There are two types of central angles. A convex central angle, which is a central angle that measures less than 180 degrees and a reflex central angle, which is a central angle that measures more than 180 degrees and less than 360 degrees.

What angle can an obtuse angle be?

90 degrees

Obtuse angles measure more than 90 degrees.

Can an inscribed angle be an obtuse angle?

Yes, the angle can get very close to (but not exactly equal to) 180 degrees. For every angle value greater than 90-degrees the chord ¯BC is smaller than the diameter.

What does a obtuse look like?

What does an Obtuse Angle Look Like? The angles measuring greater than 90° and less than 180° are called obtuse angles in geometry. The obtuse angle lies between 90° and 180° and looks like a reclined chair, an angle below the staircase, or an angle formed between a minute and an hour hand of a clock at 10:15 AM.

What does it mean to be called obtuse?

Definition of obtuse



2a : lacking sharpness or quickness of sensibility or intellect : insensitive, stupid He is too obtuse to take a hint. b : difficult to comprehend : not clear or precise in thought or expression It is also, unfortunately, ill-written, and at times obtuse and often trivial.—

Is being called obtuse an insult?

The adjective obtuse is good for describing someone slow on the uptake: “Don’t be so obtuse: get with the program!” The adjective obtuse literally means “rounded” or “blunt,” but when it’s used for a person, it means “not quick or alert in perception” — in other words, not the sharpest tool in the shed.

What does being intentionally obtuse mean?

someone who is obtuse does not understand explanations or situations quickly. I think he was being deliberately obtuse. Synonyms and related words. Words used to describe unintelligent people. silly.

What does it mean to be intentionally obtuse?

Are you deliberately being obtuse?

What did you call me? Andy Dufresne : Obtuse. Is it deliberate? Warden Samuel Norton : Son, you’re forgetting yourself.

What is an isosceles obtuse?

An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90 degrees and 180 degrees) and the other two acute angles are equal in measurement. One example of isosceles obtuse triangle angles is 30°, 30°, and 120°.

Can a triangle be scalene and obtuse?

A scalene triangle can be acute-angled or obtuse-angled or right-angled.

Can an obtuse triangle be equilateral?

Special facts about obtuse triangle:



Therefore, an equilateral angle can never be obtuse-angled. A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute.

Can isosceles be obtuse?

In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below). In a scalene triangle, none of the sides are the same length. A scalene triangle may be right, obtuse, or acute (see below).

Can a triangle have two obtuse angles?

The answer is “No”. Reason: If a triangle has two obtuse angles, then the sum of all the 3 interior angles will not be equal to 180 degrees.

How do you make a triangle obtuse?

Construction

1. Draw a horizontal line segment from point to by a ruler. …
2. Use protractor and mark a point at an obtuse angle. …
3. Take a compass and set it to any length by a ruler. …
4. Finally, join the points and by a line for completing the construction of a triangle geometrically.

What is a triangle with no sides the same?

Scalene. A scalene triangle has three different angles and none of its sides are equal in length.

Is a right triangle scalene?

A right scalene triangle is a triangle in which all three sides are different in length and one angle is equal to 90 degrees. A triangle is a closed figure made up of three lines and three angles.



Right Scalene Triangle.

Is isosceles trapezium?

In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length.

How do you remember scalene and isosceles?

Video quote: So all the sides a difference of its scalene. Whether it's also a right angled triangle. This one is similar because it is also scaling. This one here is the longest.

What is a triangle video?

Video quote: A triangle is a two-dimensional shape that has three straight sides and three angles the prefix tri means three although all triangles have three straight sides and three angles.

What is a triangle difference?

A triangle where EVERY side is different is a SCALENE triangle.

Is a scalene equilateral triangle possible?

Explanation: Note that all three sides in a scalene triangle are different. If two are of the same length and different from the third side, it’s neither equilateral nor scalene triangle.

Is a right isosceles triangle possible?

What is a Right Angled Isosceles Triangle? Yes, a Right Triangle can also be an Isosceles Triangle. The Isosceles Right Triangle has one of the angles exactly 90 degrees and two sides that are equal to each other. Since the two sides are equal which makes the corresponding angle congruent.

Are isosceles triangles always right?

No, an isosceles triangle does not always have a right angle. The only properties that a triangle must satisfy to be an isosceles triangle is that it… See full answer below.
