following figure:-​

Answer 1

Answer:

Isoceles triangle

because two angles are equal.

Answer 2

Explanation:

Given :-

the ratio of angles of triangle = 1:4:4

Solution :-

let's take the angles be x

then angles will be x, 4x, 4x

According to angle sum property,

the sum of angles of triangle is 180°

therefore, x + 4x + 4x = 180°

9x = 180°

$x \: = \: \frac{180}{9} \: = \: 20$

x = 20°

therefore,

the angles will be 1 = 20°

4x = 80 °

4x = 80°

The triangle formed is an

isosceles triangle
