Introduction
I am doing a polygon project on 5 shapes, the Square, Parallelogram, Trapezoid, acute Triangle, and an Obtuse Triangle. I will give information about these shapes and what makes them polygons. Polygons are all around us. In fact you’re looking at one now, the rectangle. A polygon is a closed shape that has sides and angles.
[3]
Square
•A square has 2 pairs of parallel sides •It has 4 equal angles and 4 equal sides •The 4 angles add up to 360* •All angles are 90* which makes it a square. •Squares are used by engineers to map blue prints for a house or building. A plane figure with four equal straight sides and four right angles.
[4]
Trapezoid
•The trapezoid is a quadrilateral. •Has one pair of parallel sides. •The parallel sides are called bases. •The four angles add up to 360* •The trapezoid only has equal sides. A trapezoid is a quadrilateral with one pair of parallel sides.
[5]
Parallelogram
•A parallelogram is a quadrilateral. •There are two pairs of parallel sides. •The four angles add up to 360*. •There are two pairs of equal sides
A parallelogram is a quadrilateral with two pairs of parallel sides.
[6]
Acute Triangle
•All sides same length. •The 3 angles add up to 180*. •The 3 angles are the same. •The angles are always less than 90*. •A triangle that has one 90* angle is no longer an acute triangle.
Equilateral
Isosceles
[7]
Obtuse Triangle
•An obtuse triangle has to have one angle more than 90* to be an obtuse triangle. •Two of the angles are less than 90*(acute). •The angles always add up to 180*. •The obtuse angle can also be called dull angles. A triangle that has an angle greater than 90*.
