FM20.4
Demonstrate understanding of properties of angles and triangles including:
  • deriving proofs based on theorems and postulates about congruent triangles
  • solving problems.

[CN, PS, R, V]

Indicators for this outcome
Note: It is intended that students be allowed to explore and use different styles of proofs, including paragraph form and two-column proofs. The emphasis should be on the logic used and the communication of that logic and not on the format of the proofs themselves.
(a)

Identify and describe situations relevant to self, family, or community that involve parallel lines cut by transversals.

(b)

Develop, generalize, explain, apply, and prove relationships between pairs of angles formed by transversals and parallel lines, with and without the use of technology.

(c)

Prove and apply the relationship relating the sum of the angles in a triangle.

(d)

Generalize, using inductive reasoning, a rule for the relationship between the sum of the interior angles and the number of sides (n) in a polygon, with or without technology.

(e)

Apply knowledge of angles formed by parallel lines and transversals to identify and correct errors in a given proof.

(f)

Explore and verify whether or not the angles formed by non-parallel lines and transversals create the same angle relationships as those created by parallel lines and transversals.

(g)

Solve situational problems that involve:

  • angles, parallel lines, and transversals
  • angles, non-parallel lines, and transversals
  • angles in triangles
  • angles in polygons.
(h)

Develop, generalize, explain, and apply strategies for constructing parallel lines.
