PQR is an equilateral triangle, and A is a point on QR such that RA = 2 QA. Prove that PA^2 = 7QA^2
If someone can help, i'd really appreciate it. Thanks

How have you attempted to prove this statement ?aek said:PQR is an equilateral triangle, and A is a point on QR such that RA = 2 QA. Prove that PA^2 = 7QA^2

aek said:Why are you answering my question with a question? Just abit ironic that's all. Thanks for the hint hyper, it was helpful.
aek said:yep i got the point,
but i too know that you have to use the cosine rule and I've tried and couldn't find a relevant answer. If you want proof that i tried, i could scan my work but you being so trustful that wouldn't be necassary :P
Plane geometry is a branch of mathematics that deals with the properties and relationships of figures and shapes that exist within a two-dimensional space, such as points, lines, angles, triangles, circles, and polygons.
The main difference between plane geometry and solid geometry is that plane geometry deals with figures and shapes in a two-dimensional space, while solid geometry deals with figures and shapes in a three-dimensional space.
Studying plane geometry helps develop critical thinking and problem-solving skills. It also provides a strong foundation for understanding more complex mathematical concepts and is applicable in various fields, such as engineering, architecture, and computer graphics.
Some common figures and shapes in plane geometry include points, lines, angles, triangles, quadrilaterals, circles, and polygons. These shapes have distinct properties and relationships that are essential in solving problems in plane geometry.
Plane geometry has various real-life applications, including designing buildings and structures, creating maps and blueprints, calculating distances and areas, and even in art and design. It is also used in navigation and GPS technology to determine the shortest distance between two points.
