Ex 5.5 Class 6 Maths Question 2.
Let $\overline { PQ }$ be the perpendicular to the line segment $\overline { XY }$. Let $\overline { PQ }$ and $\overline { XY }$ intersect in the point A. What is the measure of ∠PAY?
Solution:
The measure of ∠PAY =90° [∵ PQ ⊥ XY, given] Ex 5.5 Class 6 Maths Question 3.
There are two “set-squares” in your box. What are the measures of the angles that are formed at their corners? Do they have any angle measure that is common?
Solution:
In one, the angles are of 30°, 60°, 90° and in the other the angles are of 90°, 45°, 45°.
Clearly, the common angle = 90°

Ex 5.5 Class 6 Maths Question 4.

(b) Does PE bisect CG?
(c) Identify any two line segments for which PE is the perpendicular bisector. ‘ ’
(d) Are these true?
(i) AC > FG
(ii) CD = GH
(iii) BC< EH
