Problem 3. In triangle ABC ( not a right triangle), altitude CD is drawn to side AB. The length of AB is c. Which of the following statements must be true? The measure of angle ACB is the same measure as angle B. b^2=c^2+a^2. Triangle ADC is similar to triangle ACB. The area of triangle ABC equals \frac {1} {2}h\boldcdot c.The purpose of this Math Talk is to elicit strategies and understandings students have for calculating volumes of solids. These understandings help students develop fluency and will be helpful later in this lesson when students will need to be able to do more complex volume calculations. In this activity, students have an opportunity to notice ...

This prepares students to prove that pairs of triangles with certain properties must be dilations of one another, and therefore must be similar triangles. Note that in a later lesson, students will prove the converse of the theorems they explore in this lesson - that a segment parallel to one side of a triangle divides the other two sides ...Section C Goals. Find the area of a rectangle when one side length is a whole number and the other side length is a fraction or mixed number. Represent and solve problems involving the multiplication of a whole number by a fraction or mixed number.
