A triangle is rotated around N to give the primed version.
A. Same shape and size -- TRUE. Rotation doesn't change shape or size.
B. Corresponding points are equidistant to N. That's TRUE, each point is rotated around N to get its corresponding point, which will be the same distance from N.
C. DN=D'N. TRUE, just an example of corresponding points.
D. Corresponding side lengths unequal, FALSE. Rotation doesn't change lengths.
Given that triangle ABC is right angle triangle. CD is altitude such that AD=BC
ABC is a right angle triangle so apply Pythogorean theorem
(Given that AD = BC)
(Given that AB=3)
...(i)
ADC is a right angle triangle so apply Pythogorean theorem
...(ii)
Plug value (ii) into (i)
Hence final answer is
Answer:
o lines
Step-by-step explanation:
Answer:
49 feet squared
Step-by-step explanation:
To find the area of the square, we have to find the dimensions. If the perimeter is 28 feet, and a square has equal sides, 28 ÷ 4 = 7
Because each side of the square is 7 feet, to find the area we multiply 7 x 7.
7 x 7 = 49
I hope that this helps! :)
