## Study Notes

Geometry is a branch of mathematics that focuses on shapes and their properties. It involves understanding measurements, relationships between angles and sides, congruency, similarity, translation, rotation, and reflection. Here's what you need to know about geometry if you're studying it as part of your 10th standard curriculum:

### Points, Lines, Planes, Coordinates, and Angles

In geometry, points represent places where lines meet. They can also have coordinates that help determine their location along a coordinate plane. A line is a straight path from one point to another on a flat surface. The angle formed by two intersecting lines or segments is called an interior angle when its vertex lies inside both segments and exterior otherwise.

### Congruence and Similarity

Congruent figures share exactly the same size and shape whereas similar ones only share proportions. This means the corresponding angles and ratios of lengths of corresponding sides are equal. For example, if you flip over half circles they will still match because flipped halves are congruent; however, if you rotate squares so that diagonals are parallel, these new squares will now be similar but not necessarily congruent.

### Translation, Rotation, Reflection, Dilation

Translation moves an object across a plane without changing its orientation. Rotation turns something around a central axis while keeping everything else fixed. Reflection reflects objects through planes like mirrors do making left appear right and vice versa. Finally, dilation enlarges or shrinks objects uniformly.

Geometry uses many concepts such as symmetry, distance formulas, perimeter calculations, area computations, and more! Understanding geometry helps us understand basic spatial reasoning skills which we apply throughout our lives.
