Best Answer

There are 180 degrees total in a triangle. A right angle is 90 degrees, so two would already reach 180. (90+90=180) You need three angles to make a triangle, so if there are already 180 degrees, you can't have a third angle.

Can a triangle have to right angles?

NO, in order for a triangle to have two right angles, it would also have to have two parallel sides. This is impossible, as these two side would stretch into infinity and never close the triangele


Can a triangle with a right angle in it have another right angle in it?

No, if there was more than one right angle, it would be physically impossible for the shape to be a triangle. It would have to be a square or rectangle. Remember, all the angles in a triangle add up to 180* and two right angles alone add to 180*, therefore making it impossible for the shape to be a triangle


Which triangle has one right angle and two acute angles?

A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
