An isosceles triangle has exactly one line of symmetry.
an irregular hexagon... __/\__ \ / \ / \ /
A kite.
It is a regular pentagon!
As isosceles triangle.
A circle. One side, zero angles. Also a line as it is a 1-dimensional shape.
Yes. Think of a kite shape. Symmetry along its length but no parallel sides.
An isosceles triangle - a triangle with two sides of equal length.
A kite.
The shape you are describing is a kite. A kite has four sides, one line of symmetry (which runs through its longer diagonal), and two pairs of adjacent sides that are equal in length. This unique combination of properties distinguishes kites from other quadrilaterals.
Well, honey, that shape you're looking for is a pentagon. It's got 5 sides and just one line of symmetry to keep things nice and balanced. So, there you have it - a pentagon is the answer you've been searching for.
== == An isosceles triangle with sides 5, 5, 3. The only line of symmetry is the line joining the midpoint of the side of 3 units to its opposite vertex.
Regular polygon with any number of sides, circle, ellipse, isosceles triangle, rectangle, isosceles trapezium, kite, arrowhead.
