Question 1
1 / -0

In the given figure, magnitude of angles are ..........

A
$$40^\circ\,,120^\circ$$

B
$$30^\circ\,, 90^\circ$$

C
$$45^\circ\,,135^\circ$$

D
$$50^\circ\,,150^\circ$$

Solution
Question 2
1 / -0

BCD is a line segment and Angle BAC$$=1_{/4}$$ Angle ACB; Angle ACD$$=?$$

A
$$140$$

B
$$100$$

C
$$120$$

D
$$60$$

E
It cannot be determined from the information given
Question 3
1 / -0

In the adjacent figure, BA and BC are produced to meet CD and AD produced in E and F. Then $$\angle AED + \angle CFD$$ is ________.

A
$$80^o$$

B
$$50^o$$

C
$$40^o$$

D
$$160^o$$

Solution

In $$\triangle AED,$$
$$\angle AED+\angle EAD+90°=180°\\ =>\angle AED+\angle EAD=90°\\ =>\angle EAD=90°-\angle AED........(i)$$
Also, $$\\ \angle EAD=50°+\angle AFB.........(ii)$$ (exterior angle property)

From $$(i)$$ and $$(ii)$$, we have,
$$50°+\angle AFB=90°-\angle AED\\ =>\angle AFB+\angle AED=40°\\ =>\angle AED+\angle CFD=40°\quad (\angle AFB=\angle CFD)$$.

Therefore, option $$C$$ is correct.
