Cecile drew a 4-sided figure. It had 2 sides that were 3.4 centimeters long and 2 sides that were 3.3 centimeters long. It had a
t least 3 right angles. Which best describes the figure she drew?
1 answer:
We have two pairs of equal sides; one pair of length 3.4 cm each and one pair od 3.3 cm each.
There quadrilateral (four-sided shape) that meet this first condition is:
Parallelogram
Rhombus
Rectangle
The only shape that has at least 3 angles of 90° would be RECTANGLE as the other shapes don't have right angle
