Question

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

Answer 1

Answer:

Angles= 45°,90°,45°

Isosceles and Right-angled

Step-by-step explanation:

Ratio= 1:2:1

Sum of ratios= 1+2+1 = 4

1st angle= 1/4* 180= 45°

2nd angle= 2/4* 180= 90°

3rd angle= 1/4* 180= 45°

Therefore, the angles of the triangle are 45°,90°,45°

It is a isosceles triangle according to sides

It is a right-angled triangle according to angles

Answer 2

Answer:

angles =45°,90°&45°

the triangle is a right angled triangle and isosceles triangle

Step-by-step explanation:

$1x + 2x +1x = 180 \: degrees \\ 4x = 180 \\ x = 45 \\ 1x = 45 \\ 2x = 90 \\ 1x = 45$
