Is an equilateral triangle a quadrilateral?
Violet AldrichNo.
All triangles have three sides and three angles, hence the root word "tri" which means "three".
All quadrilaterals have four sides and four angles, hence the root "quad" meaning "four".
A triangle will never be a quadrilateral, because they do not share traits. So no, an equilateral triangle is not a quadrilateral.

Autumn ArmstrongNo, an equilateral triangle is not a quadrilateral. A quadrilateral is a polygon with four sides and four vertices, while an equilateral triangle is a triangle with three equal sides and three equal angles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Two rhombuses have sides with lengths of #15 #. If one rhombus has a corner with an angle of #(3pi)/8 # and the other has a corner with an angle of #(5pi)/6 #, what is the difference between the areas of the rhombuses?
- A parallelogram has sides A, B, C, and D. Sides A and B have a length of #2 # and sides C and D have a length of # 9 #. If the angle between sides A and C is #(3 pi)/8 #, what is the area of the parallelogram?
- How do you tessellate a quadrilateral?
- A parallelogram has sides with lengths of #15 # and #12 #. If the parallelogram's area is #42 #, what is the length of its longest diagonal?
- Two opposite sides of a parallelogram each have a length of #1 #. If one corner of the parallelogram has an angle of #(3 pi)/4 # and the parallelogram's area is #24 #, how long are the other two sides?
