Greek & Latin Prefix Tri

Explanation
The correct answer is triangle because a triangle is a three-sided figure. The other options, triathlon, triceratops, and tricycle, do not fit the description of a three-sided figure. A triathlon is a multi-sport event, a triceratops is a dinosaur with three horns, and a tricycle is a three-wheeled vehicle. Only triangle matches the given description.

Explanation
A triathlon is a race that combines three activities. The word "triathlon" is derived from the prefix "tri-", which means three, and the word "athlon," which refers to a contest or competition. In a triathlon, participants engage in three different activities: swimming, cycling, and running. They must complete all three activities consecutively, with the clock running continuously. Triathlons can vary in distance and difficulty levels, but they all involve these three activities.

Explanation
Triceratops is the correct answer because it is the only option that matches the description given in the question, which is "a dinosaur with three horns". Triceratops is a well-known dinosaur species that had three horns on its head, making it the only option that fits the given criteria. The other options, such as tricycle, trilingual, trilogy, and trio, do not relate to the description of a dinosaur with three horns.

Explanation
A tricycle is a vehicle with three wheels, making it the correct answer. The other options, such as tripod, trisect, triathlon, and triangle, do not refer to a vehicle with three wheels. A tripod is a stand with three legs, trisect means to divide into three equal parts, a triathlon is a multi-sport race with three continuous and sequential endurance disciplines, and a triangle is a polygon with three sides and three angles.

Explanation
The word "trilateral" refers to something that has or involves three sides, countries, or parties. It is derived from the Latin word "tri-" meaning three and "lateral" meaning side. In the context of the given options, "trilateral" is the only word that fits the definition. "Trilingual" means speaking three languages, "tripod" is a three-legged stand, "trisect" means to divide into three equal parts, and "triceratops" is a type of dinosaur with three horns. Therefore, the correct answer is "trilateral."

Explanation
The word "trisect" means to cut or divide something into three equal parts. This is evident in the given examples of "tripod," which has three legs, "tricycle," which has three wheels, and "triathlon," which consists of three different sports. Therefore, "trisect" is the correct answer as it aligns with the meaning and pattern of the other words provided.

Explanation
A tripod is a three-legged stool, table, or stand that is commonly used to hold things such as a camera. It provides stability and balance, allowing for steady shots or support for other objects. The other options, trilogy, trio, triangle, and trilateral, do not specifically refer to a three-legged stand and are not commonly used in this context.

Explanation
The correct answer is "trio" because a trio refers to a group of three people or things. The other options, such as tricycle, triathlon, and trilogy, do not specifically indicate a group of three.

Explanation
The word "trilogy" refers to a set of three related plays or novels. In this context, all the other words listed - tripod, triathlon, triangle, trisect - also have the common element of "tri," which means three. However, only "trilogy" specifically refers to a set of three related plays or novels, making it the correct answer.

Explanation
The word "trilingual" refers to the ability to speak three different languages. This matches the given description of being able to speak three different languages. The other options, "triathlon," "trilogy," and "triceratops," do not relate to the ability to speak multiple languages.
