Question

Construct an isosceles triangle pqr where the non equal side pq = 4.2 cm and base anles are 30 degree each

Answer 1

Answer:

An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangleThe area of the isosceles triangle is defined as half the product of base and height of a triangle. The formula to calculate the area of an isosceles triangle is (½)bh square units.

Answer 2

Answer:

Steps of construction:

Take a point M on XY and draw a line MP⊥XY

With M as centre and radius 4.5 cm, draw an arc cutting MP at A.

Construct B and C on XY such that ∠MAB =

70˚

​  

=35˚ and ∠MAC=  

2

70˚

​  

=35˚

Then ABC is the required triangle.
