## Drawing Geometric Shapes with Given Conditions

#### Aligned To Common Core Standard:

**Grade 7 Geometry** - 7.G.A.2

How to Draw Geometric Shapes Based Given Instructions (i.e., Draw a parallelogram and a triangle (right) with a 90-degree angle.) Drawing geometric shapes is not a very difficult thing to make. There is a set of pre-requisite that is required while dealing with geometric shapes. Different shapes require different instructions and data that need to be handled accordingly. For example, if you were asked to draw a parallelogram. Then you must have the basic information required for understanding the figure. First and foremost, you need to know that a parallelogram is a quadrilateral with two opposite sides parallel and equal in length. Similarly, if you are asked to draw a triangle with one ninety-degree angle, that implies that you have been asked to draw a right-angled triangle. Given this angle, we can use the Pythagoras to understand the remaining two angles of the triangle will be less than 90-degree. Here is what you will need for drawing shapes based on given instructions: The angle(s) of the figure. The specific number of sides of a figure. Students will use these worksheets and lessons to learn how to draw geometric shapes given a series of instructions.

#### Homework Sheets

For the homework we focus on triangles. They are only of those relevant shapes to this level.

- Homework 1 - Draw a quadrilateral with 4 sides, with opposite sides parallel with no right angles.
- Homework 2 - Will the lengths of all three sides of each example below create a triangle? Explain how you know which will work.
- Homework 3 - An isosceles triangle with only one 50° angle. Find the two angles.

#### Practice Worksheets

The practice sheets don't stray too far from the homework.

- Practice 1 - Draw a two dimensional shape made by drawing a curve that is always the same distance from a center.
- Practice 2 - Will the lengths of all three sides of each example below create a triangle? Explain how you know which will work
- Practice 3 - Draw a quadrilateral which has non-parallel sides equal and its base angles are equal?
