# How to see geometry at pkes 1. Lines - Lines can be straight,zigzag,curved. Intersecting lines make an angle. Parallel lines always are the same distance and never meet. A circle is a shape but not a polygon because it dose not have strait sides. A line segment is a line that has 2 end points. A ray is a line that has one endpoint and goes on and on in one direction. Perpendicular lines are lines that make a right angle. A line segment is a line with two endpoints. A point marks where something is.

2. Angles-Angles are two rays that meet at the same end point. A vertex is a shape that makes a angle. An acute angle is an angle that is smaller than 90 degrees. An obtuse angle is an angle that is more than 90 degrees. A right angle is an angle that is exactly 90 degrees.

3. Parallelogram-A parallelogram has two sets of parallel lines. A hexagon is a shape that has six sides. A octagon is a shape that has eight sides. A square is a four sided shape that has four equal sides. A rhombus is a shape that has all equal sides. A rectangle is a shape that has 2 pare of parallel lines. A triangle has three sides that can have different lengths. A trapezoid has only one pare of parallel lines. A pentagon has five sides that has no equal sides. Symmetry is a line that cuts a shape in half to make it equal. A square has all equal sides.
