If one angle of a triangle is equal to the sum of the other two angles, then the triangle is:
1 An isosceles triangle
2 An obtuse triangle
3 An equilateral triangle
4 A right triangle
Explanation:
A right triangle Let the angles of a triabgle be \(\alpha,\beta,\gamma\) Given \( \alpha +\beta =\gamma\) We now that in a sum of triangles sum of angles is \(180^\circ\) So, \(\alpha+\beta+\gamma=180^\circ\) \(\Rightarrow2\gamma=180^\circ\) \(\Rightarrow\gamma=90^\circ\) So, it is a right angled triangle.

If all the angles of a triangle measure less than 90°, then such a triangle is called ........
1 Right angled triangle
2 Obtuse angled triangle
3 Acute angled triangle
4 None of these
Explanation:
Acute angled triangle If all the angles of a triangle measure less than 90°, then such a triangle is called acute angled triangle. For eg: An equilateral triangle with all the angles equal to 60° is acute angled triangle.
