Zeda described four triangles as shown below: triangle p: two angles measure 50°. triangle q: all sides have length 13 cm. triangle r: two sides have length 3 cm, and the included angle measures 60°. triangle s: base has length 5 cm, and base angles measure 30°. which triangle is not a unique triangle? triangle p triangle q triangle r triangle s

Triangle P

Step-by-step explanation:

Given:

If any triangle have same measurement it must be similar to triangle P  by AA similarity criteria but not congruent.

Hence it is not unique.

Since all sides have same length, thus it must be an equilateral triangle with all angles  60 °.

If any triangle have same sides it must be congruent to this by SSS congruence rule.

Hence, it is unique.

If any triangle exists with same measure as triangle R then it must be congruent to triangle R by SAS congruence criteria.

Hence, it is unique.

If any triangle exists with same measure as triangle R then it must be congruent to triangle R by ASA congruence criteria.

Hence, it is unique.

e) none of the above because the measure of angle cba is 101°
