An ISOSCELES TRiangle. The line of symmetry is from the angle of the two equal adjacent sides, to the mid-point of the NON-equal side.
A regular polygon with x sides has x lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side. For example, a regular hexagon has 6 lines of symmetry, one for each pair of opposite sides. The formula for calculating the number of lines of symmetry in a regular polygon is equal to the number of sides x.
It is a regular pentagon!
The letters S and N have point symmetry but not line symmetry.
A parallelogram does not have a line of symmetry.
Isosceles triangle
A kite.
A Kite
A symmetric trapezium.
Well since isosceles can only have two equal angles and two equal sides and a triangle has 3 angles and 3 sides it can really only have 1 line of symmetry.
nothing
Sounds like an isosceles triangle, with the line of symmetry from the third angle to the mid-point of the third side.
An irregular pentagon such as a child's silhouette of a house: a rectangle shape (open at the top) forming the body of the house, with a triangular roof on of the rectangle. The vertical line through the apex of the roof is the line of symmetry. The two walls, and the two roof lines are the two sets of equal sides. The two right angles at the base are the one set of matching angles.
Only the pair of angles opposite the line of symmetry are equal. The other two angles that are bisected by the line of symmetry are not equal. if these angles were equal then the shape would be a rhombus.
A kite or an arrowhead.
It could be an arrowhead (delta) or a kite.
It has 3 sides of which 2 are equal and it has 3 interior acute angles 2 of which are equal it also has 1 line of symmetry
