JKLMN is a regular pentagon and the diagonal JL and JM are joined because of the symmetry of the pentagon all three triangles are isosceles and the left and right triangles are congruent calculate?
the all 5 sides of pentagon are identical , so all the sides are equal to each other now D is the point which is the center of the pentagon , so the bisector drawns of the angles are equal to each other therefore all the sides of the penagon are equal which says that the equilateral triangles has all the sides equal therefore the triangles are equilateral triangles
What type of triangles are there and what do they look like?
They are Similar triangles if they have the same angles. it they are exactily the same they are Equaltrial.
Some equilateral triangles are not isoscles?
They are both different types of triangles one has 3 equal sides and the other has 2 equal sides.
How many sides dose a equilateral triangle have?
Iso (same) Skelos (leg, implies side) triangle has 2 equal sides (at least), and hence has 2 equal angles (at least).An equilateral triangle (all 3 sides are equal in length, and all 3 angles are equal, which means 600 each in 3600, or PI/3 with 2PI = 360 degree ) is a special family (class) of isosceles.It has:Two equal sidesTwo equal angles♥s' Barbiee doll☺
True or false The parts of a triangle are sides vertices and angles?
true
