Can we make 2 triangles from a rectangle?
Figure 9.7. 10 – A rectangle can be divided into two triangles of equal area. The area of each triangle is one-half the area of the rectangle.
How do you find the area of a rectangle with two triangles?
Correct answer: Multiply the length of the rectangle by its width to find the area of the rectangle, and use the formula , where is the base and is the height of the triangle, to find the area of the triangle. Adding them together gives the answer.
What two triangles form a rectangle?
Answer: Green and Blue will together form a rectangle.
What are two triangles together called?

What is the truth about square and rectangle?
The Square It is also a rhombus. Therefore, all of its sides are congruent. A rectangle is a square when both pairs of opposite sides are the same length. This means that a square is a specialized case of the rectangle and is indeed a rectangle.
How do you tell if a shape is a rectangle?
How to Prove that a Quadrilateral Is a Rectangle
- If all angles in a quadrilateral are right angles, then it’s a rectangle (reverse of the rectangle definition).
- If the diagonals of a parallelogram are congruent, then it’s a rectangle (neither the reverse of the definition nor the converse of a property).
Which information is needed to show that a parallelogram is a rectangle?
Each pair of co-interior angles are supplementary, because two right angles add to a straight angle, so the opposite sides of a rectangle are parallel. This means that a rectangle is a parallelogram, so: Its opposite sides are equal and parallel. Its diagonals bisect each other.
Is every rectangle a rhombus?
No, every rectangle is not a rhombus.
Is parallelogram a rectangle yes or no?
Yes, A rectangle is considered a special case of a parallelogram because: A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.
Is a parallelogram a triangle?
A triangle is a parallelogram. This is never true. Â A triangle is a three-sided figure. Â A parallelogram is a four-sided figure with two sets of parallel sides.
What makes a parallelogram a triangle?
A parallelogram can always be decomposed into two identical triangles by a segment that connects opposite vertices. To produce a parallelogram, we can join a triangle and its copy along any of the three sides, so the same pair of triangles can make different parallelograms.
What type of triangles are in a parallelogram?
One pair of opposite sides is parallel and equal in length. Adjacent angles are supplementary. Each diagonal divides the quadrilateral into two congruent triangles. The sum of the squares of the sides equals the sum of the squares of the diagonals.
Does a parallelogram contain three triangles?
A parallelogram is consists of three triangles Both triangles and any quadrilateral is equal to 360degrees A quadrilateral is equal to 360 degrees Trapezoids can never be a parallelogram.
Can two right triangles make a parallelogram?
Parallelogram Theorem #1: Each diagonal of a parallelogram divides the parallelogram into two congruent triangles. Parallelogram Theorem #2: The opposite sides of a parallelogram are congruent….Theorems about Quadrilaterals.
