Answer and Explanation:
Equilateral triangle
An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
Isosceles triangle
An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle. It is easy to work out the missing angles of an isosceles triangle by looking for the angles that should be equal.
Scalene triangle
A scalene triangle has three different angles and none of its sides are equal in length.
Right-angled triangle
A right-angled triangle has one 90° angle. That 90° angle is shown as a small square where two sides of the triangle join. It is possible for a triangle to be a right-angled triangle and an isosceles triangle at the same time. In this case the angles would be 90°, 45° and 45°.
Obtuse-angled triangle
A triangle whose any one of the angles is an obtuse angle or more than 90 degrees, then it is called obtuse-angled triangle or obtuse triangle.
Acute-angled triangle
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
