70. $100 Question Triangle Reasoning
Can you have 2 obtuse angles in a triangle? Explain why or why not.

71. $100 Answer Triangle Reasoning
No, because that would means 2 angles greater than 90 which already adds up to over 180°.

72. Return

73. $200 Question Triangle Reasoning
What must be true about the angles in a scalene triangle?

74. $200 Answer Triangle Reasoning
They must all be different because all of the sides are different and only equal sides can have equal opposite angles.

75. Return

76. $300 Question Triangle Reasoning
Is it possible to have a right obtuse triangle? Why or why not?

77. $300 Answer Triangle Reasoning
No, because that would create an angle sum of more than 180°.

78. Return

79. $400 Question Triangle Reasoning
Why is SSA not enough to prove triangles congruent?

80. $400 Answer Triangle Reasoning
Because SSA leaves two options for a triangle. An acute option and an obtuse option.

81. Return

82. $500 Question Triangle Reasoning
Explain why an exterior angle is the sum of the other interior angles.

83. $500 Answer Triangle Reasoning
