Yes, but what does that have to do with line AC? Doesn’t line PQ intersect line BD? Let’s all look at our section 3.8 notes to see what it says about midsegments. I bet those notes will help us find the relationship between line PQ and line AC! Please look back at your section 3.8 notes about midsegments to see if you can find the relationships between lines PQ and AC. Then click here to return to Main Menu.click here Return to Main Menu

Explain your reasoning carefully. Please look back at your section 1.9 notes about quadrilaterals to determine what shape PQRS is. Then click here to return to Main Menu.click here Return to Main Menu Yes, I think so! Is PQRS a square? I think question #3 is telling us that. I don’t think we know it’s a square yet. I think that is a hypothetical question in #3. See how it says “If?” I don’t think they would give us the answer. I don’t think it tells us that AC=BD. I think ABCD would have to be a special quadrilateral to make AC=BD. Take time to answer this question before clicking again. I think PQ=SR.

Since the sides of PQRS are all midgsegments, we know that BD is twice PS (or QR). We also know that AC is twice PQ (or SR). So if PS=PQ, what does that tell us about BD and AC? In the instructions it just says that it’s a quadrilateral. It looks like an isosceles trapezoid, but I’m not sure. I’m not sure what shape ABCD is, but we know that PQRS is a square. So what characteristics does PQRS have? Return to Main Menu Take time to answer this question before clicking again. A square has all equal side lengths and all right angles. So I guess PQ=QR=RS=PS. And each of its angles is a right angle. Take time to answer this question before clicking again.
