What type of Polygon has 12 sides?
A twelve sided polygon is called a dodecagon (Doe-DECA-gon).
L and M are two parallel tangents to a circle with center O touching the circle at A and B respectively. Another tangent at C intersects the line L at D and M at E. Prove that angle DOE is 90 degrees?
Extend DO to meet M at F, then: ∠ADO = ∠OFB (alternate angles as DOF is a straight line across the two parallel lines) Using the straight line FOD: ∠DOE = ∠BEO + ∠OFB (exterior angle of a triangle = sum of other two angles) = ∠BEO + ∠ADO (substituting for equivalent angle found above) Consider triangles OBE and OCE. They are both right angle triangles as BE and CE are tangent to the circle centre O, with ∠OBE = ∠OEC = 90°. They have the same hypotenuse side OE. They have equivalent sides OB and OC equal in length (both are a radius of the circle). Thus triangles OBE and OCE are congruent by Right Angle-Hypotenuse-Side (RHS). Making ∠CEO = ∠BEO Similarly considering the triangles OAD and OCD: Both right angled triangles with ∠OAD = ∠OCD = 90° Both have same hypotenuse OD Both have equivalent side OA and OC of equal length (both are a radius of the circle). Thus triangles OAD and OCD are congruent by RHS Making ∠CDO = ∠ADO Summing the angles in triangle ODE and substituting equivalent angles (∠CDO = ∠ADO, ∠CEO = ∠BEO, ∠DOE = ∠BEO + ∠ADO) gives: ∠CEO + ∠CDO + ∠DOE = 180° →∠BEO + ∠ADO + ∠DOE = 180° → ∠DOE + ∠DOE = 180° → 2∠DOE = 180° → ∠DOE = 90° QED.

How many edges doe a cone have?
One.But it is a bit tricky and depends on how you define an edge.Many use the definition of a boundary of a geometric figurePlease see the link to the math forum at Drexel University.There is a lengthy discussion of this topic.A cone has one flat face, one curved face, one vertex and one curved edge.One.
