Sketch a right triangle, equilateral triangle, and isosceles triangle.

To determine

To Sketch: A right triangle, equilateral triangle and isosceles.


Triangle is the geometry which has three sides and three angles. Sum of all three angles are 1800.

Right angle triangle- In a right-angle triangle two sides are perpendicular to each other i.e. angle between them is 900. One angle is right angle and sum of other two angles is 900. Right angle sides are known as base and perpendicular and the other side is called hypotenuse.

Sides of right-angle triangle are calculated by Pythagorean Theorem. As per the Pythagorean theorem, for a triangle having one of the angles as 90 degree, the addition of squares of two smaller sides becomes equal to the square of the largest side of the triangle.

Sketch of Right-angle triangle.

Equilateral triangle-

This triangle has all three sides of equal length, all three angles of equal value. Total sum of the three angles is 1800...
