Unit 2 triangles

Unit 2 – Triangles

Review for Final Exam


True false

True/False

  • A scalene triangle is a triangle with no two sides the same length.


True false1

True/False

  • An obtuse triangle is a triangle that has one angle measuring greater than 90°.


True false2

True/False

  • An isosceles right triangle is a triangle with an angle measuring 90° and no two sides congruent.


True false3

True/False

  • If the base angles of an isosceles triangle each measure 48°, then the vertex angle has a measure of 132°.


True false4

True/False

  • If a triangle has two angles of equal measure, then the triangle is equilateral.


True false5

True/False

  • If a triangle has two angles of equal measure, then the third angle is acute.


True false6

True/False

  • If two sides of a triangle measure 45 cm and 36 cm, then the third side must be greater than 9 cm and less than 81 cm.


True false7

True/False

  • The sum of the measures of the three angles of an obtuse triangle is greater than the sum of the measures of the three angles of an acute triangle.


True false8

True/False

  • The incenter, the centroid, and the circumcenterare always inside the triangle.


True false9

True/False

  • An altitude of a triangle must be inside the triangle.


True false10

True/False

  • The orthocenter of a triangle is the point of intersection of the three perpendicular bisectors of the sides.


True false11

True/False

  • If is a median of and point D is the centroid, then TD = 3DR.


True false12

True/False

  • The incenter of a triangle is the point of intersection of the three angle bisectors.


Always sometimes never

Always/Sometimes/Never

If a triangle is a right triangle, then the acute angles are complementary.


Identify the point of concurrency

Identify the point of concurrency.

  • A stained-glass artist wishes to circumscribe a circle about a triangle in her latest abstract design.


Identify the point of concurrency1

Identify the point of concurrency.

  • Rosita wants to install a circular sink in her new triangular countertop. She wants to choose the largest sink that will fit.


Identify the point of concurrency2

  • Julian Chive wishes to center a butcher-block table at a location equidistant from the refrigerator, stove, and sink.


Identify the point of concurrency3

Identify the point of concurrency.

  • The first-aid center of Mt. Thermopolis State Park needs to be at a point that is equidistant from three bike paths that intersect to form a triangle.
