Triangle: 2 Marks
Given that:
The sum of two angles of the triangle is 90∘.
We know that the sum of all the three angles in a triangle is 180∘.
∴ The other angle = 180-90 = 90∘
Now we know that if one of the angles in a triangle is 90∘, then the triangle is a right-angled triangle.
Hence, the given triangle is a right-angled triangle.
