Beth wants to make a picture frame like the one pictured below. She recorded the outside
dimensions as 5 cm by 7 cm. Measure the outside
dimensions of the frame in millimeters. Compare
your measurements to Beth's. Do you think her
measurements are precise enough? Explain.

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
