Hello, john doe!
We need more information.
What is that quadrilateral on the hypotenuse . . . a square?
Is that NE-SW slanted line through the center of the square?
. . And is it parallel to the sides of the square?
Assuming all that is true, we have this diagram:Code:* * * A * * * | * * * | * * O * | * * * * | * /| * | * /θ| * | P* | * | / Q* * | / | * | | * | | * | | 30° * * * * * * * * * * * * * * C R B
We have right triangle with
A square sits on hypotenuse ; is the center of the square.
. . Actually, it could be any point in the square!
In right triangle
Then .(vertical angles)
Therefore, in right triangle
What is that quadrilateral on the hypotenuse . . . a square?
yea i think its a square it sure looks like one
Is that NE-SW slanted line through the center of the square?
yea the same it looks like its though the center
And is it parallel to the sides of the square?
i cant tell because there no indication that they are parallel
How do you know angle C is 90 degrees?
