1. What is a Pythagoras Theorem?
The Pythagoras Theorem is an important concept in Mathematics which explains the property of a right-angled triangle. The theorem states that the sum of the individual squares of the base and the perpendicular of a right-angled triangle is equal to the square of the hypotenuse.
2. What is an obtuse triangle?
An obtuse triangle can be defined as the triangle whose one angle is greater than 90 degrees and the sum of all the three interior angles equals 180 degrees.
3. What is an equilateral triangle?
The triangle where all the sides are equal in length and all the three interior angles measure 60 degrees each, then the triangle is known as an equilateral triangle.
4. What are the four properties of a triangle?
The four important properties of a triangle are:
All the three angles of a triangle are always equal to 180 degrees.
The sum of the length of two sides of any triangle is always greater than the length of the third side.
The difference in lengths of any two sides of a triangle is always less than the length of the third side.
The sum of the opposite interior angles of a triangle is equal to any of the exterior angles of the triangle.
5. Can all three sides of a triangle be different in length?
Yes, all three sides of a triangle can be of different lengths. Such triangles are known as scalene triangles. Here, the measure of all the three angles is different from each other but sums up to 180 degrees.
