• It’s a study of the realationships between shapes sizes and properties of planes and solid things on earth. Geometry
• It is the union of two non collinear rays with common endpoint. Angle
• It is a part of line consisting of two endpoint and all the point in between. Line segment
• It is a part of a line with only one endpoint and extending in only one direaction. Vertex
• An angles whose measure is 90 degrees. right angle
• An angle whose measure is than 90 but less than 180. Obtuse angle
• It is a special angle whose measure is 180. Straight angle
• It has two angles with the same vertex and a common side. Adjacent angles
• It is the unit of measurement of an angle. Degree
• It is a statement that is already true without proof. Postulate
• line is of infinite length but has no width or thickness
• Midpoint of a segment divides in to two congruent segments
• Figures or objects that can be drawn on the plane are called plane figure
• bisector of a line segment is a line segment ray or plane that intersects the segment at its midpoint
• Opposite ray are rays with a common endpoint but extending in opposite directions
• The two non collinear rays are the sides of the angle while the common endpoint is the vertex
• Point has one dimension no length blah blah blah
• The ray in the starting point are the initial sides while the second ray is called the terminal sides
• If two angles are adjacent and complementary then they form a right angle
• If two angles are adjacent and supplementary then they form a straight angle
