Triangles are polygons made up of three sides. In relation to this figure, analyze the following statements. The measure of an external angle of a triangle is equal to the sum of the measures of the non-adjacent internal angles and it. True or false An isosceles triangle is any triangle that has two sides that are congruent to each other. true or false If a triangle has two sides with equal measurements, the internal angles opposite these sides have equal measurements true or false An equilateral triangle is also isosceles true or false

Let's analyze each statement: The measure of an external angle of a triangle is equal to the sum of the measures of the non-adjacent internal angles and it. True or False: This statement is False. The measure of an external angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles, not including the external angle itself. An isosceles triangle is any triangle that has two sides that are congruent to each other. True or False: This statement is True. An isosceles triangle is defined as a triangle that has at least two sides of equal length. The congruent sides are also referred to as the legs of the triangle. If a triangle has two sides with equal measurements, the internal angles opposite these sides have equal measurements. True or False: This statement is True. In an isosceles triangle, if two sides are congruent, then the angles opposite those sides are also congruent. This is a property of isosceles triangles. An equilateral triangle is also isosceles. True or False: This statement is True. An equilateral triangle is a special type of isosceles triangle where all three sides are congruent. Therefore, an equilateral triangle satisfies the criteria for being an isosceles triangle. In summary: Statement 1: False Statement 2: True Statement 3: True Statement 4: True
