3. The three angles of a triangle are in the ratio 1:2:1. Find all the angles of the triangle.
Classify the triangle in two different ways.​

Answer 1

Answer:

45,90,45

This traingle is a right angle traingle .

Step-by-step explanation:

$1 \div 4 \times 180 = 45 degree \\ 2\div 4 \times 18 = 90degree \\ 1 \div 4 \times 180 = 45degree$

Answer 2

LET THE 1 : 2 : 1 are 1x : 2x : 1x

= 1x + 2x + 1x = 180 ( Angle Sum Property Of Triangle )

= 4x = 180

= x = 180 /4

= x = 45

1X = 45 × 1 = 45

2X = 45 × 2 = 90

1X = 45 × 1 = 45
