Geometry Worksheets. We cover a wide range of geometry concepts. We focus primarily on angles, shapes, perimeter and area. For detailed geometry worksheets, see the geometry packs.You can also compare students' measurements of the same objects to see if they got the same measurement. Let's say, you had 20 students measure the height of the doorway. You should get 20 very similar answers (unless they are the sharing type then you'll get exactly the same answers) and any different answers can be quickly identified. Explain whether the triangles are similar. Two angles in the large triangle are congruent to two angles in the smaller triangle, so the third pair of angles must also be congruent, which makes the triangles similar. 70° + 36° + m∠3 = 180° m∠3 = 74° 8.G.1.5 Use informal arguments to establish facts about the angle sum and exterior angle of
