Question

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???





please answer ​

Answer 1

Let the angles of the triangles be x,2x\:\:and\:\:x

So,

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

x+2x+x=180^0

4x=180^0

x=45^0

2x=90^0

Hence the angles of the triangles are 45^0,90^0 and 45^0.

On the Basis of sides, the triangle is isosceles triangle as two sides of the triangle are equal.

On the Basis of angle, the triangle is Right-Angled Triangle as it has one angle equal to 90 degrees

Answer 2

Answer:

$\huge{\underline{\orange{H}\blue{E}\red{L}\purple{L}\green{O}}}$

Step-by-step explanation:

let original angles be x , 2x , x according to ratio

then sum of all angles in a triangle = 180

x+2x+x=180

4x = 180

x= 180/4

x= 45

2x= 90

$\therefore \\ angles \: are \: 45, \: 90, \: 45$
