✅ lines
✅ line segments
✅ rays
✅ acute angles
✅ obtuse angles
✅ right angles
✅ isosceles right triangles
✅ equilateral acute triangles
✅ scalene obtuse angles
✅ congruent figures

This unit includes a total of 5 visual and kinesthetic activities for students, and 4 worksheets. These lessons should take about a week to complete.

This geometry unit contains:

✅ Types of line relationships demonstration and activity

### Standards

to see state-specific standards (only available in the US).
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
An angle that turns through 𝘯 one-degree angles is said to have an angle measure of 𝘯 degrees.
