Point a is the point of concurrency of the angle bisectors of δdef. point a is the point of concurrency of triangle d e f. lines are drawn from each point of the triangle to point a. lines are drawn from point a to the sides of the triangle to form right angles and line segments a x, a y, and a z. the length of f a is 6 centimeters, the length of a d is 5 centimeters, the length of a x is 3 centimeters, and the length of y d is 4 centimeters.
what is the length of za?
a) za = 3cm
b) za = 4cm
c) za = 5cm
d) za = 6cm

A) ZA = 3 cm

Step-by-step explanation:

The triangle is shown below.

From the triangle, A is the concurrency point of angle bisectors of all vertices.

Consider ΔAYD,

Using Pythagorean theorem,

Consider triangles ADY and ADZ.

The two triangle are congruent by AAS postulate.

Therefore, by CPCTE,

3x + 4y -25 =0 represents the amount of change sianna should recieve

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
