In this activity we will explore what happens when we construct the three perpendicular bisectors of the sides of an acute triangle, a right triangle, and an obtuse triangle. Before you begin, you must make sure your calculator is in degree mode and not in radian mode. Do this by pressing the home key and selecting . 8: System Info, then

Young students, for example, might notice that three and seven more is the same amount as seven and three more, or they may sort a collection of shapes according to how many sides the shapes have. Later, students will see 7 × 8 equals the well remembered 7 × 5 + 7 × 3, in preparation for learning about the distributive property.

The triangle on the right is an equilateral triangle, in which all three sides and angles are equal. The vertical line is an altitude, meeting the side in a right angle. Using this information, but with no knowledge of what the numerical lengths of the side or altitude are, find the sine and cosine of the angle at B.
