Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

Question

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Chapter 1.3, Problem 20CE

To determine

To state: Whether the given figures appear to be congruent.

Expert Solution & Answer

Answer to Problem 20CE

Yes. Both figures (triangles) appear to be congruent.

Explanation of Solution

Given information: Consider the figure showing two line angles.

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 1.3, Problem 20CE

Concept used: Two figures are called congruent, if both have the same shape and size. Or, if all their corresponding parts are equal.

Calculation: In shown figure, all the corresponding angles as well as all corresponding sides of these two triangles seem equal to each other. That means,

In the given figure, two triangles are shown. Thus, the shape of both the figures is the same.

All the corresponding angles as well as all corresponding sides of these two triangles seem to be equal to each other.

Thus, the sizes of both the triangles are the same.

Conclusion: So, the triangles appear to be congruent.
