Learn and practice identifying, drawing and, measuring different types of angles and become an expert in angles with interactive resources from GeoGebra.
Adding and Subtracting AnglesUse addition and subtraction to find unknown measures of non-overlapping angles.
AnglesIdentify and label the vertex, rays, and interior and exterior of an angle. Use appropriate naming conventions to identify angles.
Drawing and Measuring Angles with a ProtractorDraw and measure angles using a protractor. Understand that a circle measures 360 degrees.
Types of AnglesIdentify and draw angles (acute, right, obtuse, and straight).
Angle Sum Properties of Triangles, Quadrilaterals, and PolygonsUse a variety of triangles, quadrilaterals, and other polygons to draw conclusions about the sum of the measures of the interior angles.
Complementary and Supplementary AnglesDefine and identify complementary and supplementary angles.
Lines and AnglesDefine and identify alternate interior, alternate exterior, corresponding, adjacent and vertical angles.
Pairs of AnglesUse properties, definitions, and theorems of angles and lines to solve problems related to adjacent, vertical, complementary, supplementary, and linear pairs of angles.
Using Theorems for Angles Formed by Parallel LinesUse definitions and theorems of angles formed when a transversal intersects parallel lines.
