Answer 2

The triangle with the required values is constructed and the image is attached below.

Given:

Triangle ABC has AC = 4cm

∠A = 80°

∠B = 50°

To find:

The ΔABC is to be constructed.

Solution:

The steps of construction are as follows.

A straight line AC of length 4 cm is drawn .

At A an angle of value 80° is drawn using a protractor.

Next at C an angle with value 50° is drawn using a protractor.

The lines that are formed by theses two angles meet at B.

In the ΔABC ,

∠A = 80°

∠B = 50°

Hence ∠C = 180°- (50° + 80°) = 50°

Therefore the triangle formed is a Isosceles triangle which has the two base angles equal.
