On a piece of paper, use a protractor to construct right triangle DEF with DF=8 cm, m∠E=30°, and m∠F=90°. Which statement is true about this triangle?

DE=4 cm

EF=4 cm

DE=16 cm

EF=16 cm

Which statement is true 1.the pythagorean theorem can be used to find the missing side of any triangle 2.the pythagorean theorem can be used to find the missing side of any polygon 3. the pythagorean theorem can be used to find the missing side of any right triangle 4.the pythagorean theorem can be used to find the missing side of any isosceles triangle

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?
