In an isosceles triangle the base angle is twice as large as vertex angle find the angles of the trian
In an isosceles triangle , base angles are equal
LET vertex angles be x
Then, Base angles will be 2x and 2x
SUM OF ANGLES OF TRIANGLE IS 180°.
Therefore,
2x + 2x + x = 180°
5x = 180°
=> x = 36°
ANSWER =
VERTEX ANGLE = 36°
BASE ANGLES ARE EQUAL TO = 36° × 2
= 72° & 72°
