Which type of figure Cannot have 2 or more right angles?

Right Angles: Which Shapes Just Can’t Handle the Turn?

Right angles. We see ’em everywhere, don’t we? They’re the perfect 90-degree corners that make up squares, rectangles, and, well, a whole lot of buildings. But here’s a fun fact: not every shape plays nice with multiple right angles. So, what’s the one shape that simply can’t have more than one of these perfect corners? It’s the triangle!

The Triangle’s Tricky Angle Situation

Think about it: a triangle has three sides, right? Now, here’s the kicker: all those inside angles have to add up to 180 degrees. It’s like a strict rule they gotta follow. And that’s precisely why you can’t cram more than one right angle in there.

Imagine trying to build a triangle with two right angles. Each one is 90 degrees. Add ’em together, and you’re already at 180 degrees! That leaves nothing for the third angle. Zip. Zilch. Nada. You’d end up with a flat line, not a triangle. Trust me, I tried drawing it once, back in high school geometry. Didn’t work!

Other Shapes? No Problem!

Now, other shapes? They’re not so angle-challenged.

• Quadrilaterals: Take squares and rectangles. They’re practically made of right angles – four of ’em each! And even a right trapezoid gets in on the action with two right angles.
• Pentagons: Believe it or not, some pentagons can even squeeze in three right angles. It’s a bit unusual, but totally doable.

The Right Triangle Exception

Okay, so there is something called a right triangle. This is a triangle that has one right angle. The other two angles? They have to be smaller than 90 degrees, and together they also have to add up to 90 degrees. It’s all about keeping that 180-degree total in check.

The Bottom Line

Right angles are super important in geometry, no doubt. But the triangle? It’s a bit of a rebel. It can only handle one right angle, max. It’s just part of its nature, that angle-sum thing. So, next time you see a triangle, remember its unique limitation. It’s what makes it, well, a triangle!
