GDE is equilateral . For help have a look at ry1
Well, this is one of the simplest examples of similar triangles and ratios of their sides. Have a look at ry1.
A quadrilateral with exactly one pair of parallel sides is called a ... .
Remember the previous questions .
Diagonals of a rhombus are perpendicular .
Draw parallelograms and see what happens as the lengths of diagonals get closer and closer .
Remember triangle inequality .
Interior sides are not included as we consider perimeters .
The whole square is of unit area .
3-4- ... right triangle is a well known triangle. Pythegorean Thorem gives the length of its hypotenuse but it is too early to learn this theorem.
We wanted you to get acquainted with the triangle and to find the length of the hypotenuse with the facts you already know.
Just for remembrance because of importance .
Just two of them make a rhombus .
