Identifying the Congruent Parts
Write the corresponding side or angle as directed, taking hints from the notation convention followed in the congruent statement, which includes information about which sides and angles correspond.
Similarity | Check for Similar Triangles
Compare the corresponding sides of the given pair of triangles. If the sides are proportional, then the two triangles are similar.
Scale Factor Word Problems - Level 1
Solve these real-life word problems to find the attributes like length, width and distance of model or real objects.
Dilation with Center at Origin | Writing the Scale Factor
Look at the images A and B with their centers at the origin on the coordinate plane and write the scale factor.
Congruence | Write the Congruence Statement
Write the corresponding angle to complete the congruence statement for each pair of triangles.
Similar Triangles | Find the Side
The corresponding sides of similar triangles are always proportional. Form an equation of proportion and solve it to find the side length.
Scale Factor | Find the Missing Side
A number of similar shapes with scale factors in whole numbers is illustrated here. Find the length of the labeled sides.
Congruence | Indicate the Congruent Angles and Sides
Read the given congruence statement and mark the corresponding sides and angles in each pair of triangles.
Scale Factor | Perimeter of Similar Figures
Apply the given scale factor of the two similar figures to determine the perimeter of the original or the scaled image.
Scale Factor | Area of Similar Figures
Compute the missing area of the original image or the scaled image by applying the area of similar polygons' theorem.
Dilation with Center at Origin | Finding New Coordinates
To find the new coordinates of a dilated image, just multiply the scale factor with the given coordinates.
Algebra in Similar Triangles | Solve for x
In each pair of similar triangles, one of the dimensions is given as an algebraic expression. Set up a proportion and solve for x.
Scale Factor | Surface Area of Solid Similar Figures
Use the relationship between the scale factor and surface area and find the surface area of the enlarged or reduced image.
Scale Factor | Volume of Similar Figures
Figure out the volume of the original or dilated solid shape by using the scale factor and the known volume.
Scale Factor | Mixed review - MCQ
