Can Noncongruent polygons have unequal corresponding side lengths?
True
Which polygon appears to be regular?
Polygons that have equal side lengths are regular as for example an equilateral triangle
If the ratio of the side lengths of two similar polygons is 31 what is the ratio of the perimeters?
Their perimeters are in the same ratio.
Does opposite sides are parallel means the same?
No. Parallel means they are side by side and have the same distance continuously between them but they might be different lengths and therefore not the same. A trapezoid has two parallel sides of unequal lengths.
The noncongruent side of an isosceles triangle is called what?
base (legs are the two congruent sides)
Can Noncongruent polygons have unequal corresponding side lengths?
True
Can a congruent polygon have unequal corresponding side lengths?
No, the definition of congruent polygons is that all corresponding SIDES are of equal length. All corresponding angles as well.
Two two-dimensional polygons are if their side lengths are proportional?
similar
What shapes have all equal side lengths?
They are called regular polygons
Are polygons with all right angles sometimes squares?
Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.
What do you call polygons that have equal angles and proportional side lengths?
a double triangle
Congruent polygons must have all corresponding side lengths equal?
true
Why can a square also be a rhombus but can never be a trapeoziod?
Trapezoids have unequal side lengths.
Which polygon appears to be regular?
Polygons that have equal side lengths are regular as for example an equilateral triangle
Is a concave polygon regular?
No! Regular polygons must have equal side lengths and equal angles.
What polygon is an equiangular polygon?
All regular polygons are equiangular because their side lengths are equal.
Can you have two polygons having corresponding side lengths that are proportional and can you conclude that the polygons are similar?
No. You could, for example, have a square and a rhombus with sides twice as large.
