Ch. 3 Test (Part II) Review

  • Median: Divides side to which it is drawn into two congruent segments.

  • Altitude: Forms right angles with the side to which it is drawn.

  • Draw all medians/altitudes of triangle

  • Circles: All radii are congruent

  • Isosceles Triangles: At least two congruent sides and congruent base angles. (Mark sides/angles congruent!!)

  • Overlapping triangles: Draw triangle separately to label SSS, SAS, or ASA.

  • Prove triangles congruent by H.L.rt. <

  • Auxiliary Lines

  • Properties

Solve for x:


Solution mark congruent segments and angles

Solution: Mark congruent segments and angles!!!


Sometimes always never

Sometimes/Always/Never

A right triangle has two acute angles.


Sometimes always never1

Sometimes/Always/Never

A right triangle has two acute angles.

Answer: ALWAYS (one angle is 90 degrees, so sum of other two must equal 90 – must be acute!)

ALWAYS (definition)


Sometimes always never7

Sometimes/Always/Never

Triangles are congruent if two pairs of corresponding sides and a pair of corresponding angles are congruent.

Sometimes/Always/Never

Triangles are congruent if two pairs of corresponding sides and a pair of corresponding angles are congruent.
