Answer 1

Answer:

In a triangle, the sum of the three interior angles equals two right angles. In the words of Euclid: In any triangle, if one of the sides be produced, the exterior angle is equal to the two interior and opposite angles, and the three interior angles of the triangle are equal to two right angles.

Answer 2

2 right angles = 90°+90°

= 180°

180° is a straight angle

so 2 right angles= a straight angle
