Triangles and Quadrilaterals

Triangles

the only regular triangle is a equelateral triangle
the measurments equal to 180 degrees
a triangle has 3 sides and angles

Constucting triangles

step five: label the measurment and the triangle for clarity
step four: join the arc point to the line you made
step three: make an arc with thecompass
step two: take your compass and bring it to the needed measurments
step one: make a straight line segament

Quadrilaterals

a quadrilateral's measurment equal to 360 degrees
the only regular quadrilateral is a square
a Quadrilateral is a shap with 4 sides and 4 angles
