a circle
An acute triangle.
Both congruent and similar figures are types of geometric figures that share specific relationships. Congruent figures have the same shape and size, meaning all corresponding sides and angles are equal. In contrast, similar figures have the same shape but may differ in size; their corresponding angles are equal, and their sides are proportional. Ultimately, both types of figures maintain certain geometric properties that define their relationships.
The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.
Circle, cone, cylinder, sphere and equilateral triangle for example.
right
All triangles that are not right triangles.
They are similar.

To find and compare measures of angles, you can use a protractor to measure the angle in degrees or radians directly. Alternatively, you can use geometric relationships, such as complementary angles (summing to 90 degrees) or supplementary angles (summing to 180 degrees), to deduce their measures. For comparison, you can visually assess the angles or calculate their measures algebraically if they are part of geometric figures. Finally, using trigonometric functions can also help in finding and comparing angles in right triangles or circles.
