This resource consists of two interactive excel programs.
Angle Facts presents students with questions relating to angles on a straight line, angles at a point, and angles in triangles and rectangles. The sheet on angles and parallel lines does not use the words "corresponding" or "alternate" but the F or Z shape can be shown on the diagram. There are three interactive sheets on angles in scalene, isosceles and equilateral triangles. There are a further thirteen sheets of questions suitable for duplication for classroom use.
Triangles: What Type, Angles, Area The first two sheets show a triangle on a coordinate grid. Students can calculate the length of sides, the angles and the area of each triangle. Alternatively, students can click to reveal the lengths and angles and state the type of triangle. The third sheet shows a triangle, the size of angles can be revealed and students say whether the triangle is scalene, equilateral or isosceles. There are a further eight sheets of questions on similar topics suitable for duplication for classroom use.
