There are 10 squares that are constructed as shown in the diagram. Find the difference between blue and red angle in degrees.
Blue=30 degrees red=15 degrees
3 identical 30°, 60°, 90° right triangles are arranged as shown in figure. What is the ratio between greed and red line?
Three identical squares are shown in the diagram. If the area of the triangle is 1 square meter, what is the area of a single square?
If the red angle is 10 and the blue one is 30, what is the measure of green angle?
If in each square, the blue and red areas are equal then find out the ratio of radius between big and small circle?
What is the measure of angle EDF shown in the diagram below?
You can assume AB is the diameter of a semicircle, C is on the arc of the semicircle, and D, E, F are points of tangency between the inscribed circle I and the triangle ABC.
