Name the three different types of proofs you saw in this lesson. Give a description of each.
The three types of proofs are two-column proofs, paragraph proofs, and flowchart proofs. A two-column proof organizes statements and reasons into two columns. A paragraph proof describes the logical steps and reasons using sentences in a paragraph. A flowchart proof uses boxes and arrows to visually represent the progression of steps and logical flow.
Sample Response: One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof. What did you include in your response? Check all that apply.Two-column proofs are in columns and list statements and reasons.Paragraph proofs use words.Flowchart proofs give a visual representation of the progression of

Identify the missing parts in the proof.
✔ measure of angle ABC = 90measure of angle ABC = 180measure of angle ABD = 90 measure of angle CBD = 180

angle ABC = 90 angle ABD = 90 2 times the measure of angle ABC = 90 ✔ 2 times the measure of angle CBD = 90
