What is the length of AG where G is the centroid of triangle ABC?
ABC is right angle triangle, where AB = 300 and BC = 400. What is the length of the blue link?
Triangle ABC has a right angle at B. Let Q be along BC and P be along AB such that AQ bisects angle A and CP bisects angle C. If AQ = 9 and CP = 8√2, what is the length of the hypotenuse AC?
In rectangle ABCD, point G is the midpoint of AD, and points E and F trisect BC. The diagonal BD intersects GE at H and GF at I. If the area of ABCD is 10, what is the area of triangle HIG?
Assume triangle ABC can be divided into 6 smaller triangles, as shown below, with the areas given. What is the area of the entire triangle ABC?
Triangle ABC is an isosceles triangle with AB = AC and A = 100°. Extend the ray from A to B until point D such that AD = BC, as shown below. What is the measure of angle BDC?
