measures less than 90 degrees.
$200 Question from Under one
Condition
What is the converse and inverse of the following statement:
If ABC is equilateral, then it is isosceles.
Converse: If ABC is isosceles, then it is equilateral.
Inverse: If ABC is not equilateral, then it is not isosceles.
$300 Question from Under one
Condition
Write the following statement as a conditional, and write its
contrapositive.
All obtuse angles have measure greater than 90.
Conditional: If an angle is obtuse, then it has measure greater
than 90.
Contrapositive: If an angle does not have measure greater than
90, then it is not obtuse.
$400 Question from Under one
Condition
Write the converse, inverse, and contrapositive of the following
conditional.
If a triangle is a right triangle, then it has a 90 degree angle.
Converse: If a triangle has a 90 degree angle, then it is a right
triangle.
Inverse: If a triangle is not a right triangle, then it does not have a
90 degree angle.
Contrapositive: If a triangle does not have a 90 degree angle, then it
is not a right triangle.
$500 Question from Under one
Condition
Write the converse, inverse, and contrapositive of the following
conditional, and determine the truth value of each.
If two angles have measure 90, then the angles are congruent.
Converse: If two angles are congruent, then they have measure 90.
Truth Value: False
Inverse: If two angles do not have measure 90, then they are not
congruent.
Truth Value: False
Contrapositive: If two angles are not congruent, then they do not
have measure 90.

Conclusions
Consider the following conditional statement. If the
conditional and it’s converse are true, write it as a
biconditional.
If three points are collinear, then they lie on the same line.
Three points are collinear if and only if they
lie on the same line.
$200 Question from Possible

an isosceles triangle.
A triangle is an isosceles triangle if
and only if it has two sides of equal
length.

If m < 1 = m < 3, order the steps given to prove that m < 2 = m < 4.
1 2
1. By the Angle Addition Postulate, m < 3 + m < 4 = 180.
2. Prove: m < 2 = m < 4.
3. By substitution, m < 3 + m < 2 = m < 3 + m < 4.
4. By the Angle Addition Postulate, m < 1 + m < 2 = 180.
5. Given: m < 1 = m < 3
6. m < 1 + m < 2 = m < 3 + m < 4, by the Transitive Property
of =.
7. Subtract m < 3 from both sides, and you get m < 2 = m < 4.
