Answer:
The midpoint theorems says that the line made by joining the two midpoints of the two sides of a triangle is always parallel to the third side of the triangle. The length of the midsegment is half the length of the third side.
Step-by-step explanation:
Given:
Area of a square frame = 81 square inches.
To find:
Perimeter of the frame.
Solution:
Let length of each side of the frame = a inches.
Area of square frame is
Taking square root on both sides,
Side length cannot be negative. So, a=9 inches.
Perimeter of frame is
Therefore, the perimeter is 36 inches.
The perimeter of the frame is 36 inches.
To find the perimeter of a square, we need to know the length of its sides. Since the area of the frame is given as 81 square inches, we can find the length of one side by taking the square root of the area. The square root of 81 is 9, so each side of the frame measures 9 inches.
Since a square has four equal sides, we can find the perimeter by multiplying the length of one side by 4. Therefore, the perimeter of the frame is 9 inches x 4 = 36 inches.

Answer:
Dilation by a scale factor of 2 followed by a reflection over the y axis.
Step-by-step explanation:
The Y-axis is the vertical axis. So that cancels out the two about the x-axis. Then I counted the length of both triangles bases. Luckily for this one their bases aren't tilted but just flat. The big one is 6 and the small 3. Since it is going from one to the other you must find what number completes their equation. 3x = 6.
