The following picture shows the line from 2nd to home making a right triangle.
a2+ b2= c2
(27x27) + (27x27) = c2
729m(squared) + 729m(squared) = c2
1458= c2
✔1458cm(squared)= ✔c2
38.18m= c
The following picture shows a right triangle. Find h/ c .
a2 + b2= c2
(6x6) + (10x10) = c2
36cm(squared) + 100cm(squared)= c2
136cm2= c2
✔136cm(squared) =✔c2
11.66cm= c
The following picture shows a right triangle. You are only given r & t. Find s.
a2 + b2 = c2
20(squared) + b2= 52(squared)
(20x20) + b2 = (52x52)
b2= 52(squared) - 20(squared)
b2= 2704- 400
b2= 2304 cm(squared)
✔ b2= ✔2304
b= 48cm
The following picture shows a right triangle. You are only given b and c. Find a.
a2 = c2 - b2
a2 = 9(squared) - 4(squared)
a2= 81cm2 - 16cm2
a2= 65cm
✔a2= ✔65cm
a= 8.06 cm

Questions 1, 2, 3 and 4.
Question 1:
Jack must determine the side length of a right triangle. He decides to draw it, and then measure it, as shown. Do you agree with the method that Jack is using? Explain .
I agree with the method Jack is using, because once he knows what the two side lengths are, he can find the hypotenuse.
Question 2:
Kira calculated the missing side length of the right triangle.
Is Kira correct ? If she is correct, explain how you know. If she is incorrect, explain the correct method.
Kira is not correct, because she forgot to do this part:
194cm(squared) = y2
✔194= ✔c2
13.9= c
