A comprehensive guide for learning all about Coordinate geometry with definitions, the coordinate plane, formulas, equation of a line, related topics, solved examples, and practice questions.

Explore the world of Euclidean geometry by understanding euclidean and non-euclidean geometry, the postulates and axioms, and how to apply them while solving problems. Check-out the solved examples for better understanding and try your...

This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying...

Explore the process that changes the shape, size or position of a figure to create a new image, transformations.

An extensive discussion of the Elements, which contains all the geometrical knowledge available in the Hellenistic period.

In this task, seven pennies are placed in a circle so that they are all touching one in the center and their neighbors. Students are asked to find as many rigid motions of the plane as they can which are symmetries of this configuration...

Use this calculator to calculate the distance between 2 points by entering 2 sets of coordinates in the 3-dimensional Cartesian coordinate system, (X1, Y1, Z1) and (X2, Y2, Z2), to get the distance formula calculation for the 2 points...

Alex and his friends are studying for a geometry test and one of the main topics covered is parallel lines. They each write down what they think it means for two distinct lines in a plane to be parallel. Students are asked to analyze...

For this task, students are shown a unit circle in a plane and an angle measured from the x-axis. They must determine the coordinates of the line segment for the angle and answer a question about the sum of the coordinates. The purpose...

Use the law of sines to calculate unknown angles or sides of a triangle. In order to calculate the unknown values, you must enter 3 known values.

An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees.

Use this calculator to calculate physical values related to the shape of a stadium.
