ch.7 true or false
midsegment of a triangle
A segment whose endpoints are the midpoints of two sides.
similar polygons have to have the same side lengths but same angles (same shape)
false because they do not have to have the same sides, and angles
in convex polygon all angles would not be the same
false they would be the same
scale factor is not a ratio written as a fraction
false, it is a ratio written as a fraction
side-splitter
line parallel to one side of a triangle separates the other two sides proportional
if two triangles are similar then the measures of corresponding sides are proportional to...
measure of corresponding altitudes, angle bisectors, and medians
if two triangles are similar then the perimeters are proportional to...
measures of corresponding sides
side-side-side
measures of corresponding sides of 2 triangles are proportional
side-angle-side
measures two side lengths of one triangle are proportional to measure of two corresponding side lengths of another triangle, included angles are congruent
what does the angle bisector do?
separates the side opposite the angle into segments that have the same ratio as the other two sides.
corresponding polygons must have corresponding sides and angles must be equal
true
in order for a polygon to be similar it must have congruent angles
true
not every right triangle is similar to other right triangles
true
two polygons are similar if and only if their corresponding angles are congruent and their corresponding sides are proportional
true
angle-angle
two angles of one triangle are congruent to two angles of another triangle then they are similar
