Скачать или смотреть Understanding Triangle Properties | 5.G.B.4 💛💙

In this short math video we will use our understanding of triangle properties to answer a standardized math test question. We will review the definition of an isosceles triangle. We will understand that an isosceles triangle can sometimes be a right isosceles triangle. We will discuss that an equilateral triangle is also an isosceles triangle. We will review that the three interior angles of a triangle have a sum of 180 degrees. A modeled exemplar solution is provided.
