Answer:

The correct option is;

An isosceles triangle

Step-by-step explanation:

The parameters given are;

Line segments XY and ZY are tangents to circle O.

ΔXYZ has points X and Z on the circle.

XY and ZY are tangents that intersect at point Y outside the circle'

Therefore, given the circle has center O, then;

OY ≅ OZ = Radius of circle with center O

∠OXY ≅ ∠OZY = 90° (The radius line from the circle center to the tangent point is perpendicular)

OY ≅ OY (Reflexive property)

ΔOYX and ΔOYZ are right triangles (Triangle with one angle = 90°

ΔOYX ≅ ΔOYZ (Hypotenuse Leg, HL, rule of congruency)

Therefore;

XY = ZY (Corresponding Parts of Congruent Triangles are Congruent CPCTC)

Triangle XYZ is an isosceles triangle (Triangle with two equal sides).

What is the format of this proof? Given: ∠ABC is a right angle, ∠DBC is a straight angle Prove: ∠ABD is a right angle two-column

borishaifa [10]

Answer: Two column proof.

Explanation :

A two-column proof is one common way to organize a proof in geometry.Two-column proof always has two columns where one for statements and one for reasons.

Here,

$\angle ABC$ is a right angle and $\angle DBC$ is a straight angle( $180^{\circ}$ ) . (given)

Therefore, $\angle ABD$ must be right angle. ( because, $\angle ABD=\angle DBC-\angle ABC= 180^{\circ}-90^{\circ}=90^{\circ}$ )

Which is the required proof.

Since, In the above proof both statements and reasons both mentioned, therefore, it is the two column proof.

Note: We can also make a table which consist of two columns, in first we can mention 'statements' while in second column we can mention 'reasons'.

Gemiola [76]

Answer:

Equilateral type of Triangle is created.

Step-by-step explanation:

Incenter: It is a point of intersection of angle bisector of three angles of a triangle.

Circumcenter: It is a point of intersection of perpendicular bisector of three sides of a triangle.

For an Equilateral Triangle points incenter and circumcenter must coincide (same). Hence the type is Equilateral Triangle

borishaifa [10]

Find each probability separately and then multiply the two together

Probability for even number is 3/6 or 1/2 because their are 3 even numbers out of 6 numbers

Probability to get a black chip is 1 black chip out of 3 totals so 1/3

Multiply 1/3 by 1/2

Answer 1/6
