Question

1. The measures of the exterior angles of a triangle are 140 and 130 respectively
Which type of triangle is it?

(1) Acute angled triangle
2) Obtuse angled triangle
3)Right angled triangle 4)Equilateral triangle​

Answer 1

Answer:

3) Right angled triangle

Step-by-step explanation:

Given exterior angles of a triangle are 140 and 130 then the interior angles are 40 (180- 140) and 50 (180 - 130), so the third angle is 90, by angle sum property( Sum of interior angles of any triangle is 180)
