This page presents two additional flow chart proof examples, focusing on consecutive interior angles and supplementary angles in geometry.
Given: m∠7 = 125°, m∠8 = 55° Prove: l || k (lines l and k are parallel)
The proof uses the following steps:
Definition: Consecutive interior angles are pairs of angles on the same side of a transversal between two lines. When these angles are supplementary (add up to 180°), the lines are parallel.
Given: a || b, ∠1 = ∠2 Prove: c || d
This proof demonstrates the use of the converse of the consecutive interior angles theorem:
Example: In this problem, the congruence of angles 1 and 2, combined with the parallel lines a and b, leads to the conclusion that lines c and d are also parallel.
Highlight: These proofs demonstrate the importance of understanding the relationships between parallel lines, transversals, and the angles formed by them in geometric reasoning.
Both problems on this page reinforce the concept of consecutive interior angles and their role in determining parallel lines, showcasing the application of Triangle flow chart Proofs in more complex geometric scenarios.
This page introduces flow chart proof examples in geometry, focusing on complementary angles and their relationships. The practice problem presented involves proving that two angles are congruent using given information about complementary angles.
The flow proof begins with the given information:
The goal is to prove that angle 1 is congruent to angle 3.
Definition: Complementary angles are two angles that add up to 90 degrees.
The proof utilizes the following steps:
Highlight: The flow chart format allows for a visual representation of the logical steps in the proof, making it easier to follow the reasoning process.
The proof concludes by demonstrating that angles 1 and 3 are congruent, and angles 2 and 4 are congruent. This is achieved through the use of the congruent complements theorem and the properties of complementary angles.
Vocabulary: Flow proof - A method of organizing geometric proofs using a flowchart-like structure to show the logical progression of steps.
