Answer:

Acute, Equilateral

Step-by-step explanation:

Acute because all angles (which are 60 degrees) are less than 90 degrees.

Equilateral because all sides are equal.

Answer:

The correct options are

A. Acute

E. Isosceles

F. Equilateral

Step-by-step explanation:

From the figure we can see a triangle.

<u>To find the correct options</u>

1). From figure we get all the angles are equal.

Each angle is equal to 60°

60 < 90

Option A. Acute is TRUE

2). Also all the sides of the triangles are equal,

Therefore the given triangle is equilateral triangle.

Option F. Equilateral is TRUE

Every equilateral triangle is Isosceles triangle.

Therefore option D. is also true

Which graph shows a function whose inverse is also a function?

never [62]

Answer: A good way to determine if a line represents a valid function is to use the vertical line test.

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time.

If it is touching more than one point on the line at a time, the line is not a valid function.

The first line and its inverse both pass the test.

The second line passes the test, but its inverse does not.

The third line also passes the test, but again, its inverse does not.

The same applies to the fourth line and its inverse.

Answer:

Option (4).

Step-by-step explanation:

In the figure attached,

Two right triangles ΔXYZ and ΔTUV have been given,

Given:

1). m∠Y = m∠U = 30°

2). m∠Z = m∠V = 60°

3). m∠X = m∠T = 90°

For congruence of two right triangles, measure of at least one side should be known along with the measure of angles (LA, HA, LL, HL properties of congruence).

Therefore, these triangles may be similar but not congruent.

Option (4) is the correct option.

Answer:

See explanation

Step-by-step explanation:

Consider triangles ACM and BCM. In these triangles,

$m\angle 3=m\angle 4$ - given;
$m\angle 1=m\angle 2=90^{\circ}$ - definition of perpendicular lines CM and AB;
$\overline{CM}\cong \overline{CM}$ - reflexive property.

So,

$\triangle ACM\cong \triangle BCM$ by ASA postulate (if one side and two angles adjacent to this side of one triangle are congruent to one side and two angles adjacent to this side of another triangle, then two triangles are congruent).
