FAQs on Infographics: Types of Traingles - Mathematics (Ganita Prakash) Class 7 - New NCERT

1. What are the different types of triangles based on their sides?
Ans. Triangles can be classified into three types based on their sides: equilateral, isosceles, and scalene. An equilateral triangle has all three sides equal in length. An isosceles triangle has two sides equal and one side different. A scalene triangle has all sides of different lengths.
2. How can triangles be classified based on their angles?
Ans. Triangles can also be classified based on their angles into three categories: acute, right, and obtuse. An acute triangle has all angles less than 90 degrees. A right triangle has one angle exactly equal to 90 degrees. An obtuse triangle has one angle greater than 90 degrees.
3. What is the sum of the angles in a triangle?
Ans. The sum of the interior angles of any triangle is always 180 degrees. This is a fundamental property of triangles regardless of their type.
4. Can a triangle have more than one right angle?
Ans. No, a triangle cannot have more than one right angle. If a triangle has one right angle, the other two angles must be acute, ensuring that the total sum remains 180 degrees.
5. How do you determine if three lengths can form a triangle?
Ans. To determine if three lengths can form a triangle, you can use the triangle inequality theorem. The sum of the lengths of any two sides must be greater than the length of the third side. This must hold true for all three combinations of side lengths.
