FAQs on Examples: Triangles Video Lecture - Mathematics (Maths) Class 6

 1. What are the different types of triangles?
Ans. There are several types of triangles based on their angles and sides. The different types of triangles based on angles are acute, right, and obtuse triangles. Based on sides, triangles can be classified as equilateral, isosceles, or scalene triangles.
 2. How do you calculate the area of a triangle?
Ans. The area of a triangle can be calculated using the formula A = 1/2 * base * height, where A represents the area, base is the length of the base of the triangle, and height is the perpendicular distance from the base to the opposite vertex.
 3. What is the Pythagorean theorem and how is it related to triangles?
Ans. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This theorem is commonly used to solve problems involving right triangles.
 4. Can a triangle have more than one right angle?
Ans. No, a triangle cannot have more than one right angle. A right angle measures exactly 90 degrees, and the sum of the interior angles of a triangle is always 180 degrees. Therefore, if one angle is a right angle, the other two angles must be acute.
 5. How can you determine if three given side lengths form a triangle?
Ans. To determine if three given side lengths can form a triangle, you can use the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If this condition is satisfied for all three combinations of side lengths, then a triangle can be formed.
