FC: Shapes and design project By : Addison Ramirez

1: This is an example of an Isosceles triangle. An Isosceles triangle has two congruent sides as you can see in the picture. What helps me think of the Isosceles triangle is this jingle, "Isosceles two E's two congruent sides." An Isosceles triangle has three angles, vertices, and sides. One of the angles has a different degrees.One way of measuring the angles are 50 degrees, 50 degrees, and 80 degrees. The total angle sum is 180 degrees. | This is an example of a Scalene triangle. A Scalene triangle has no equal sides,vertices, angles that are congruent.The angle sum is 180 degrees. One of the angles is 70 degrees, another 30 degrees, and 80 degrees .

2: Right Triangle | This is an example of a right triangle. A right triangle has a right angle. The total angle sum is 180 degrees. | Obtuse triangle | This is an example of an obtuse triangle. Obtuse triangles have an obtuse angle. The total angle sum is 180 degrees.

3: Acute triangle | This is an example of an acute triangle. Acute triangles have at least two acute angles. The total angle sum is 180 degrees. | This is an Equilateral triangle.An equilateral triangle has three vertices, sides, and angles. Each angle equals 60 degrees. The total angle sum is 180 degrees.

4: This is a rhombus. A rhombus has four sides, vertices, and angles. Each angle of a Rhombus is 60 degrees. The total angle sum of a rhombus is 360 degrees. | This is an example of a non-square rhombus. The total angle sum is 360 degrees. It is not a square because a square has all right angles and non-square rhombus are acute and right.

5: This is an example of a square which is a quadrilateral. You can see in the bottom right corner Laurie and I have formed a square. A square has four sides, angles , and vertices. Each angle in a square is 90 degrees. The total angle sum of a square is 360 degrees. | This is an example of an irregular quadrilateral. The sides and angles of an irregular quadrilateral are not equal. The total angle sum is 360 degrees.

6: This is an example of a pentagon. A pentagon has five sides, vertices, and angles. | The angle sum of a pentagon is 540 degrees. Each angle is 108 degrees. | This is an example of an irregular pentagon. An irregular pentagons sides and angles are not equal.

7: This is an example of a hexagon. | A hexagon has six angles, vertices, and sides. Each angle is 120 degrees. The total angle sum is 720 degrees. | This is an example of an irregular hexagon. The angles and sides of an irregular hexagon are not equal.

8: This is an example of a heptagon. Each angle of a heptagon is 128.5 degrees. The total angle sum of a heptagon is 900 degrees.

9: This is a example of an octagon. Each angle of a octagon is 135 degrees. the angle total sum of a octagon is 1,080 degrees. | This is an example of an irregular octagon. An irregular octagons sides and angles are not equal.

10: This an example of a decagon. A decagon has 10 sides, angles,and vertices.Each angle is 144 degrees. The angle sum of a decagon is 1,440 degrees. | This is an example of a irregular decagon. irregular decagons sides and angles are not equal.
