Question

The angles of the triangle ABC are in the ratio of 1:2:1. Determine the
corresponding angles. What type of a triangle is this?

Answer 1

Answer:

The angles are in the ratio = 1 : 2 : 1

let the angles be 1x, 2x, 1x

We know that,

The sum of the triangle = 180 degree

$1x + 2x \: + 1x \: = 180 \: degree$

$4x \: = 180 \: degree$

$\: x \: = \: 180 \: \div 4$

Therefore

$x \: = 45 \:$

the sides are 1 ×45 = 45

2 ×45 = 90

1 ×45 = 45
