Does length CD touch side AB at a right angle?
If so, from pythagoras...
(CA)sq = (CD)sq x (0.5x(AB))sq
so...
CD=sqrt[(CA)sq / (0.5x(AB))sq]
sq = squared
sqrt = square-root
put all your known numbers in the bold equation
An equilateral triangle
An isoceles triangle has TWO sides of equal length but an equilateral triangle has THREE sides of equal length
a equilateral triangle has all the sides the same length.
The original statement is: "If a triangle has three sides of the same length, then it is equilateral." Inverse: "If a triangle does not have three sides of the same length, then it is not equilateral." Converse: "If a triangle is equilateral, then it has three sides of the same length." Contrapositive: "If a triangle is not equilateral, then it does not have three sides of the same length."
All three sides of an equilateral triangle are..."equal" in length.
That depends on what is meant by length of AD but the 3 sides of an equilateral triangle are all equal in lengths.
is called an equilateral triangle

an equilateral triangle
A triangle with equal length sides
The original statement is: "If a triangle has three sides of the same length, then it is equilateral." Inverse: "If a triangle does not have three sides of the same length, then it is not equilateral." Converse: "If a triangle is equilateral, then it has three sides of the same length." Contrapositive: "If a triangle is not equilateral, then it does not have three sides of the same length."
All three sides are equal in length.
An equilateral triangle is one whose three sides are the same length.
All three sides of an equilateral triangle are..."equal" in length.
