Similar - Two triangles are similar if all their corresponding angles are equal and their corresponding sides have the same ratio.Congruent - Two triangles are congruent if all of their corresponding sides and angles are equal.Exterior angle theorem - The measure of an exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.Triangle inequality - The sum of the lengths of two sides of a triangle is always larger than the length of the third side the difference between the lengths of any two sides is less than the length of the third side.The sum of the exterior angles of a triangle is always equal to 360° Angle sum property - The sum of the interior angles of a triangle is always equal to 180°.The longest side of a triangle is opposite the angle with the largest measure and the shortest side of the triangle is opposite the smallest angle. The lengths of the sides of a triangle correspond to the measures of their angles the larger the angle, the larger the side the smaller the angle, the smaller the side.A triangle is a polygon with 3 sides, 3 angles, 3 vertices.An obtuse triangle also cannot be equilateral. A triangle cannot be both obtuse and right (or acute).The side opposite the largest angle measure is the longest side of the triangle.In other words, the square of the longest side of an obtuse triangle is always greater than the sum of the squares of its shorter sides. The other two angles in the triangle are acute angles ( a 2 + b 2.
