Hello, I'll be taking trigonometry next semester and thought i should learn its foundations, and one of them is geometry. I went through Khan Academy to look for topics and i found bunch of them. However, i sent the topics to an ai to confirm if all of these are a must and it replied with a list of topics that arent needed. I just wanna know from actual people.

Here are the topics from khan academy:

1. Intro to area and perimeter

Count unit squares to find area

Area formula intuition

Multiply to find area

Area and the distributive property

Decompose figures to find area

Perimeter intro

Perimeters of polygons with missing side lengths

Perimeter word problems

Comparing area and perimeter

Area versus perimeter
2. Intro to mass and volume

Mass

Volume
3. Measuring angles

Parts of plane figures

Angle introduction

Angle types

Understanding angle measurement

Measuring angles

Decomposing angles
4. Plane figures

Quadrilaterals introduction

Classifying triangles

Parallel and perpendicular

Classifying geometric shapes

Lines of symmetry

More on quadrilaterals

Properties of shapes
5. Units of measurement

Estimating length

Converting units of mass

Converting units of volume

Converting units of length

Conversion word problems (larger to smaller)

Converting to larger or smaller

Converting metric units word problems
6. Volume

Volume with unit cubes

Volume of rectangular prisms

Decompose figures to find volumes

Volume word problems
7. Coordinate plane

Intro to the coordinate plane

Coordinate plane word problems

Points in all four quadrants

Problem solving in all quadrants

Area of triangles

Area and perimeter on the coordinate plane

Area of composite figures
9. 3D figures

Surface area with nets

Finding surface area

Slicing geometric shapes

Volume and surface area word problems
10. Circles, cylinders, cones, and spheres

Area and circumference of circles

Area and circumference of fractions of circles

Volume of cylinders, spheres, and cones
11. Angle relationships

Vertical, complementary, and supplementary angles

Missing angles problems

Parallel lines and transversals

Triangle angles
12. Scale

Scale copies

Scale drawings
13. Triangle side lengths

Constructing triangles

Pythagorean theorem

Pythagorean theorem application

Pythagorean theorem and distance between points
14. Geometric transformations

Transformations intro

Translations

Sadly, mass and volume is usually not needed for trigonometry

For the foundational perspective, definitely make sure you look at the different types of angles and triangles; especially right triangles. Also, make sure you are comfortable with the skills and knowledge gained from college algebra (e.g. functions and their graphs, solving equations, etc.).

All you really need are knowledge about triangles (area, angles, and specifically right triangles)

#

It's possible the questions may touch on other subjects of geometry, but you should just focus on this
