Geometry Unit 2 lesson 1&2

Write the statement in conditional form. The midpoint of a line segment is equidistant from the endpoints.

• If a line segment has equidistant endpoints, then it is a midpoint.

• If the endpoints are equidistant from a line segment, then it is a midpoint.

• If a point is equidistant from the endpoints of a line segment, then it is a midpoint.

• If a midpoint is equidistant from the endpoints, then it is a line segment.

they observe in their community during a 24-hour period. A sample result is listed

below. Use the graph to see trend as needed.

species the volunteers will observe in 2025 if the trend continues.

If the trend continues, volunteers will observe about ___ bird species.
