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.

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