Samuel Chukwuemeka (Samdom For Peace) B.Eng., A.A.T, M.Ed., M. Use the check boxes to see the actual reflections. Think about what the reflection across the y-axis would look like. Step 2: Extend the line segment in the same direction and by the same measure. Since the reflection line is perfectly horizontal, a line perpendicular to it would be perfectly vertical. Think about what the reflection across the x-axis would look like. Step 1: Extend a perpendicular line segment from A A to the reflection line and measure it. With a reflection calculator, you can solve any of the reflection problems easily. Drag points A, B, and C to other positions in the first quadrant to change the shape of triangle ABC. Use A Reflection Calculator To Solve All Types Of Reflection Equations. If you are my student, please do not contact me here. Reflecting a triangle across the x-axis and the y-axis. Please check back for the remaining ones later.Ĭomments, ideas, areas of improvement, questions, and constructive criticisms are welcome. The calculators should work.Īt the moment, only the calculators for the Translations, Reflections, and Rotations are completed. Explore this lesson to learn what a reflection is and use our step-by-step calculator to learn how to perform reflections over horizontal, vertical. above matrix by the shown reflection matrix. Input up to 10 shape (x,y) coordinates below: X: Y: Click any button below to multiply the. In this activity, students explore reflections over the x-axis and y-axis, with an emphasis on how the coordinates of the pre-image and image are related. I wrote the codes for these calculators using Javascript, a client-side scripting language. Basic math, GED, algebra, geometry, statistics, trigonometry and calculus practice problems are available with instant feedback. Then use the calculators to check your answers. You are encouraged to: solve the questions graphically (by construction) verify the solutions algebraically (by formulas) Third: solve the questions/solved examples.įourth: check your solutions with my thoroughly-explained solutions.įifth: check your answers with the calculators as applicable.
