do you know what an isosceles triangle is?
OpenStudy (anonymous):
Yeah I do. Its just that the AC=TC part confused me.
OpenStudy (anonymous):
I meant CT
OpenStudy (jdoe0001):
right, well those are just labels for the vertex points, that is where each side meets, well, draw one here :), use the whiteboard
OpenStudy (jdoe0001):
lemme give you 3 segments so you can assemble them|dw:1378241012761:dw|

Something like this/?
OpenStudy (jdoe0001):
yeap, in a isosceles triangle, only 2 sides have to be EQUAL
now, none of the INTERNAL ANGLES in the triangle are 90 degrees or more than 90 degrees, all 3 angles are less than 90 degrees, that means all angles are ACUTE
that makes it an ACUTE ISOSCELES triangle
so which 2 sides are equal?|dw:1378241365055:dw|

AC AND CT
OpenStudy (jdoe0001):
yeap, that's all they meant by saying AC = CT
