Warm Up Use what you know about 30, 60, 90 triangles to find the missing sides!
Rectangular Solid • Face • Edge AB is one of 12 edges • Diagonal HB is one of 4 diagonals ABFE is one rectangular face out of the 6 faces H G E F O C A B
Cube • A rectangular solid in which all edges are congruent. What is the diagonal of each side? 3 3 3
Regular Square Pyramid • Square base Bottom of the pyramid. • Vertex • Altitude • Slant height Point where the edges of the triangles meet. Distance from vertex to the base. It is perpendicular to the center of the base. Height of the triangles, perpendicular to the base of the triangle.
Try this: find HB Keep your answer in reduced radical form.
