If the original conditional statement is true, then the contrapositive will always be false.

Find the value of x.  The diagram shows two nested triangles, with the smaller triangle inside the larger one. A horizontal segment measuring 7 units divides the larger triangle. The left side is made of two segments, both labeled 11 units. The right side consists of a 10-unit segment above the horizontal and a lower segment labeled “x minus 2”. The base of the larger triangle is labeled 14 units. All sides are outlined in black, forming a proportional nested triangle configuration.

Bioarchaeology is best defined as:

Which postulate or theorem, if any, could you use to show the two triangles are congruent?  Two triangles intersect at a central vertex, forming a crisscross, slanted hourglass shape. The triangle on the left points to the right, and the triangle on the right points to the left. An interior angle is marked with an arc at the bottom left vertex of the left triangle and at the top right vertex of the right triangle. A tick mark appears on the bottom slanted side of the left triangle and the top slanted side of the right triangle, indicating that these two sides are congruent. All segments are drawn with bold black lines.

Two triangles are congruent, and their congruency statement is . Based on the congruency statement, which of the following statements are true? Select all that apply.

Kinship refers to socially recognized relationships between people. “Fictive kinship” specifically means:

An angle bisector of an equilateral triangle always divides the triangle into two congruent triangles

Find the circumcenter of the triangle. A triangle is plotted on a coordinate grid. The x-axis spans from below negative 6 to above 5, and the y-axis spans from negative 5 to above 4, both marked at intervals of one. The triangle’s vertices are labeled as (negative 4, 2), (negative 4, negative 1), and (0, negative 1). The left side is a vertical segment connecting (negative 4, 2) and (negative 4, negative 1). The bottom side is a horizontal segment from (negative 4, negative 1) to (0, negative 1). The hypotenuse connects (0, negative 1) to (negative 4, 2).

Find the circumcenter of the triangle. A triangle is plotted on a coordinate grid. The x-axis spans from negative six to five, and the y-axis spans from negative four to six, both marked at intervals of one. The triangle’s vertices are at (negative 3, 3), (negative 3, negative 2), and (1, negative 2). The left side is a vertical segment from (negative 3, 3) to (negative 3, negative 2). The bottom side is a horizontal segment from (negative 3, negative 2) to (1, negative 2). The diagonal side, forming the hypotenuse, connects (1, negative 2) to (negative 3, 3).

Under the UNESCO Convention on the Protection of Underwater Cultural Heritage, underwater traces of human existence that are 100 years old or more are protected.
