a. Sketch the triangle. Draw a square on each side of the triangle.
b. What are the areas of three squares?
c. Write and addition statement with the areas of three squares .
10.) A triangle has side lengths of 120 mm, 160 mm, and 220 mm. Is the triangle a right triangle? Eplain your reasoning.
Correction: for c2 its suppose to be 40,000.
Yes it is a right triangle. I used this formula
15)Consruction workers have begun to dig a hole for swimming pool. They want to check that the angle they have dug is 90 degrees. They measure they diagonal as shown to be 9.5 m. Explain your reasonings.
No its not a right angle because in my calculation the hypotenous should be 10 to be a right angle.
19.) A right triangle has a square attached to each side. Two of the squares have areas of 10 cm2 and 15 cm2. What are possible areas for the third square? Draw a sketch for each solution.
The possible areas for the third square is
5 cm and 25 cm.
How I got the anwer: a2+b2=c2 for 25 cm
and c2-b2=a2 for 5 cm.
Here are some math games.
