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

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!)
