Types of Triangles

Mrs. Altenburg said...

Could you explain the different types of triangles based on the number of sides and the types of angles.

Yes, Mrs. Altenbury,

We can answer that question for you. There are six different types of triangles. There is a right triangle, obtuse triangle, and acute triangle. They are different because of their angles. The right triangle has a 90 degree angle. The obtuse triangle is different because one angle is greater than 90 degrees. The acute triangle is smaller than 90 degrees and all the angles are smaller than 90 degrees. The other three triangles are Scalene, Isosceles and Equilateral. The Scalene triangle has no congruent sides. The equilateral triangle has all congruent sides, and the Isosceles triangle has two equal sides.
