A pizza slice is a triangle with two sides that are equal in length. They must be marked as congruent (look for the tick marks) or if the measurements are not already given, measure them to check the length of each side. A triangle is a three-sided closed plane shape with three vertices and three angles. It is represented by the symbol . Triangle M: Since at least two sides have the same equal measure, this triangle is an isosceles triangle. A triangle with three vertices, A, B, and C, is represented as ABC. We use symbols in geometry. If the angle is 90, the triangle is a right triangle. The error in measurement will change the classification. Because its angles are equal, an equilateral triangle is also known as an equiangular triangle. WebA person can classify a triangle based on the side lengths (equilateral, isosceles, or scalene), and by the angle measures (acute, right, or obtuse).
