Given : Three angles of a triangle are cut off and lined up on the line . 2 lines form a V and come out of the line. The middle angle formed is 90 degrees, and the right angle is 45 degrees.
To Find : which statements are true
Solution:
The sum of the three angles is 90° is False
as one angle itself is 90°
The sum of the angles in the triangle is 180°. - TRUE
The three angles are adjacent and form a straight angle. TRUE
45° + 90° + 45° = 180°
The third angle is 45° - TRUE
as 180° - 90° - 45° = 45°
There is a pair of congruent angles. - TRUE
45° = 45°
