There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
The three angles of a triangle is as a result of these three types of a triangle: equilateral, isosceles and scalene.
Right Angle, Acute Angle, and Obtuse Angle
Only three types of angles can be formed by two intesecting lines. Obtuse, acute, and right.
scalene-unequal length sides and unequal anglesisosceles-two equal length sides(legs) and two equal anglesequilateral- three equal length sides and three equal angles

There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
The three angles of a triangle is as a result of these three types of a triangle: equilateral, isosceles and scalene.
The three basic types of triangles are equilateral, isosceles, and scalene. An equilateral triangle has three congruent (equal) sides and three sixty-degree angles. An isosceles triangle has two congruent sides and the two angles opposite those sides are also congruent. A scalene triangle has no congruent sides or angles.

Triangles can be classified into different shapes. Equilateral ; All sides the same length ; all angles equal 60 degrees. Isosceles ; Two sides the same length ; two angles equal size. Right-Angled ; Three sides can be of different lengths ; MUST have one right-angle. Scalene ; All sides of different lengths ; all angles of different size. Common 2-dimensioanal characteristics for ALL triangles. ; - They contain three(3) sides They contain three(angles) The internal angles ALWAYS sum to 180 degrees. A triangle may also be named a TRIGON ; A polygon of three sides. NB Triangles drawn on a 3-dimensional surface ( sphere ), the above characteristics can vary.
A triangle has three sides and three angles.
A triangle has three angles.
There are right angles, acute angles, obtuse angles, and straight angles.
A triangle has three internal angles and three external angles, for a total of six angles.
