Geometry

In math we've been learning geometry. Here are the things that we're learning in geometry.

Lines and Rays: Lines go forever and rays have one stopping point and go forever in one way. When you say your making a line you are actually making a line segment. Line segments have a stoping point on both ends.

Line Relationship: Parallel line will NEVER touch. An intersecting lines touch/cross. L T t are perpendicular lines. Perpendicular lines make a square corner.

Angles: Acute angle's lines are closer together than other types of angles. Right angles make a square corner and are also known as a 90 degrees angle. Obtuse angles open more than a right angle.

Polygons: Triangles are a three sided shape and  have three sides. Quadrilaterals have four sides and four vertices. Pentagons have five sides and five vertices.  Hexagons have six sides and five vertices. An octagon has eight sides and eight vertices.

Triangles: Equilateral triangles have equal sides. Scalene triangles have no sides the same. Isosceles triangles have two sides the same.

Quadrilateral= 4 sided polygon: Parallelograms have parallel sides. A rhombus has equal sides and is a parallelogram. A rectangle has all right angles and is a parallelogram. A square has all right angles and equal sides, it's also a rhombus, rectangle, and parallelogram. There's also non-parallelograms. The most common one is a trapezoid. They have one pair of parallel sides.
