FAQs on Infographics: Kinds of Triangles - Mathematics (Maths) Class 7 (Old NCERT)

1. What are the three main types of triangles?
Ans. The three main types of triangles are equilateral triangles, isosceles triangles, and scalene triangles.
2. How are equilateral triangles different from isosceles triangles?
Ans. Equilateral triangles have all three sides of equal length, while isosceles triangles have two sides of equal length.
3. Can a triangle have two right angles?
Ans. No, a triangle cannot have two right angles. The sum of the angles in a triangle is always 180 degrees, so having two right angles would exceed this total.
4. What is the Pythagorean Theorem and how is it related to triangles?
Ans. The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This theorem is commonly used to find missing side lengths in triangles.
5. How can you determine if a triangle is obtuse, acute, or right-angled based on its angles?
Ans. An obtuse triangle has one angle greater than 90 degrees, an acute triangle has all angles less than 90 degrees, and a right-angled triangle has one angle that is exactly 90 degrees.
