FAQs on Examples: Angle Sum Property of a Triangle Video Lecture - Crash Course: Class 9

1. What is the angle sum property of a triangle?
Ans. The angle sum property of a triangle states that the sum of the three interior angles of a triangle is always equal to 180 degrees.
2. How can I calculate the measure of an angle in a triangle?
Ans. To calculate the measure of an angle in a triangle, you can use the angle sum property. Subtract the measures of the other two angles from 180 degrees to find the measure of the remaining angle.
3. Can a triangle have two right angles?
Ans. No, a triangle cannot have two right angles. The sum of the three interior angles of a triangle is always 180 degrees, and if two angles are already 90 degrees each, the third angle would have to be zero degrees, which is not possible.
4. What happens if the angles of a triangle do not add up to 180 degrees?
Ans. If the angles of a triangle do not add up to 180 degrees, then it is not a valid triangle. In Euclidean geometry, the sum of interior angles of a triangle is always fixed at 180 degrees, and any deviation from this sum would indicate an error or inconsistency.
5. Is the angle sum property applicable to all types of triangles?
Ans. Yes, the angle sum property is applicable to all types of triangles, whether they are equilateral, isosceles, or scalene. The sum of the interior angles will always be equal to 180 degrees, regardless of the triangle's shape or side lengths.
