Question

A traffic police signal board is in the shape of a triangle marked with "SCHOOL AHEAD" displayed on the road side. The vertices of this triangle are R(-3a, 0), Q(3a,0) and P(0, 3a$\sqrt{3}$)
Plot these points on the graph. Join PR and PQ. What type of triangle is formed ?

Answer 2

Step-by-step explanation:

Given:A traffic police signal board is in the shape of a triangle marked with "SCHOOL AHEAD" displayed on the road side. The vertices of this triangle are R(-3a, 0), Q(3a,0) and P(0, 3a$\sqrt{3}$)

To find:Plot these points on the graph. Join PR and PQ. What type of triangle is formed ?

Solution:

Here R(-3a,0), Q(3a,0) and P(0,3a√3)

Mark these points on graph,assuming every entry as a,2a,3a,4a...in right and -a,-2a,-3a,-4a... in left of zero on x-axis ,same way on above and below on y-axis.

Join the points .

Triangle PQR is attached.

PQR is an isosceles triangle,because Point R and Point Q are equidistant from P.

Thus,sides PR=PQ

Final answer:

∆PQR is an isosceles triangle.
