Q. 2

Triangle DEF of Fig. 6.6 is a right triangle with E = 90°.



What type of angles are D and F?
A. They are equal angles

B. They form a pair of adjacent angles

C. They are complementary angles

D. They are supplementary angles

Answer :

Given: Δ DEF is a right triangle with E = 90°


Formula Used/Theory:-


Sum of all angles of triangle is 180°


In Δ DEF


D + E + F = 180°


D + 90° + F = 180°


D + F = 180° - 90°


D + F = 90°


Angle D and F are complimentary angles


As their sum is 90°
