Question

If the angle of a traingle are in the ratio 1:2:3, find the angles. Classify the traingle in two different ways

Answer 1

Step-by-step explanation:

Let the angles of the triangles be x , 2x , 3x

So, we know the sum of internal angles of a triangle is 180.

x + 2x + 3x = 180° (angle sum property of triangle)

= 6x = 180°

= x = 180°/6

= x = 30°

Then Angles are :

x = 1×30° = 30°

2x = 2×30° = 60°

3x = 3×30° = 90°

∴One angles is 90 ∘

∴It is a right angled triangle.

∴Sides an different.

∴It is a scalene triangle.

Answer 2

Answer:

x = 1×30° = 30°

2x = 2×30° = 60°

3x = 3×30° = 90°
