Answer:
Option B is correct.
The reflection rule is followed here is, 
.
Explanation:
Since, the triangle is reflected over the x-axis , then only y- coordinates will get changed but the x coordinates will remain the same.
Therefore, the only reflection rule on the coordinate plane that verifies the triangle are congruent when reflected over x-axis is,
Answer:
A cube is a special prism which has bases and faces that are all squares. A pyramid is a polyhedron with only one base. The shape of the base determines the specific name of each pyramid. The faces are always triangles that meet at a common vertex.
Step-by-step explanation:
Answer:
Thus, the expression to find the measure of θ in radians is θ = π÷3
Step-by-step explanation:
Given that the radius of the circle is 3 units.
The arc length is π.
The central angle is θ.
We need to determine the expression to find the measure of θ in radians.
Expression to find the measure of θ in radians:
The expression can be determined using the formula,
where S is the arc length, r is the radius and θ is the central angle in radians.
Substituting S = π and r = 3, we get;
Dividing both sides of the equation by 3, we get;
