Question

On a piece of paper, use a protractor to construct a triangle with angle measures of 100° and 30°.

Answer 1

The third angle measures 50° and all sides have different lengths.

What is a triangle?

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled.

The sum of angles in a triangle is 180 degrees.

A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:

x + 100 + 30 = 180° (sum of angles in a triangle)

x = 50°

Also, all sides have different lengths since all the angles are different.
