Hazri prepared another two pencils and he aligned them as shown in the diagram above.
The two pencils form an angle which is labelled () in the diagram. If the angle of the pencil tip is and the angle of the pencil tip is , then what is the value of ?
(Assume the pencils have a rectangular body and have their tips resembling isosceles triangles)
Three squares are joined together as shown in figure to create a triangle.
What is the sum of angles ?
Note: We are referring to the "exterior angles", not the interior angles of the triangle.
As shown in the diagram above, there lie 3 squares between 2 parallel lines such that each pair--(line, square) or (square, square)--just meet at a vertex. Find the measure of angle in degrees.
In the figure above, and are equilateral triangles. Find in degrees.
