Which statement about their volumes is true? (Recall the formula V = 5B.)
All three pyramids have the same volume.
All three pyramids have different volumes.
Only pyramids 1 and 2 have the same volume.
Only pyramids land 3 have the same yolume

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
