**Ex 5.5 Class 6 Maths Question 1.**

Which of the following are models for perpendicular
lines:(a) The adjacent edges of a table top.

(b) The lines of a railway track.

(c) The line segments forming a letter ‘L’.

(d) The letter V.

**Solution:
**(a) Yes, the adjacent edges of a table top are the
models of perpendicular lines.

(b) No, the lines of a railway tracks are parallel to each other. So, they are not a model for perpendicular lines.

(c) Yes, the line segments forming the letter ‘L’ are the model for perpendicular lines.

(d) No, the line segments forming the letter ‘V’ are not a model for perpendicular lines.

**Ex
5.5 Class 6 Maths Question 2.**

Let PQ be the
perpendicular to the line segment XY. Let PQ and XY intersect in the point A. What is the
measure of ∠PAY?**Solution:
**Since PQ ⊥ XY.

∴ ∠PAY = 90°

**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:
**The figures of the two set-squares in all geometry
boxes are given below:

The measure of angles of set-square (b) are: 45°, 45° and 90°.

Yes, they have a common angle of measure 90°.

**Ex
5.5 Class 6 Maths Question 4.**

Study the diagram. The line *l*is perpendicular to line

*m*.

(a)
Is CE = EG?

(b) Does PE bisects 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

**Solution:
**(a) Yes.

Since, CE = 2 units and EG = 2 units

Hence, CE = EG.

(b) Yes, PE bisects CG because E is the mid-point of CG.

(c) The line segments for which PE is the perpendicular bisector are: DF and BH.

(d) (i) True (ii) True (iii) True
