Geometry
Geometry is a branch of mathematics that studies the properties, measurement, and relationships of points, lines, angles, surfaces, and solids. From basic lines and angles to complex structures, it helps us understand the world around us.

Geometry – FAQs
What is geometry in math?
Geometry is a branch of mathematics that deals with the properties, relationships, and measurements of points, lines, angles, shapes, and spaces.
What are some fundamental types of geometry?
The fundamental types of geometry are : Euclidean geometry, Plane geometry, Solid geometry, Coordinate geometry( Analytical geometry ) , Non – Euclidean geometry, Trigonometry.
What are the basic types of angles in geometry?
The basic angles are acute (less than 90°), right (90°), obtuse (greater than 90° but less than 180°), and straight (180°).
What is the difference between congruent and similar shapes?
Congruent shapes have the same size and shape, while similar shapes have the same shape but different sizes (proportional dimensions).
What are the properties of parallel lines?
Parallel lines never meet, are equidistant from each other, and have the same slope when represented on a coordinate plane.
