Parentheses!! Don’t forget PEMDAS! (Parentheses, exponents, multiplication, division, addition, subtraction)
Melanie said:
Every angle bisector in a triangle bisects the opposite side perpendicularly.
A 'counterexample' would show an angle bisector in a triangle that DOESN'T
bisect the opposite side perpendicularly.
See my attached drawing of a counterexample.
Both of the triangles that Melanie examined have
equal sides on both sides
of the angle bisector. That's the only way that the angle bisector can bisect
the opposite side perpendicularly. Melanie didn't examine enough different
triangles.
Answer:
Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.
Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.
Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.
Recall that one of the properties of a rectangle is that opposite sides are parallel.
Notice that line AB and CB are the opposite sides of the rectangle ABCD.
Thus, line AB and CD are not intersecting but are parallel.
Therefore, the terms that best describe lines AB and CD are
parallel
noncollinear
coplanar

Answer:
40 + 18 = 58 or 34 + 24 = 58
Step-by-step explanation:
1. cut the figure into two shapes
2. multiply the length and the width for both figures (write the area for each figure after multiplying each figure)
3. add the areas of each figure together
