Anaheim, California

Anaheim (pronounced /ˈænəhaɪm/) is a city in Orange County, California, part of the Los Angeles metropolitan area. As of the 2010 United States Census, the city had a population of 336,265, making it the most populous city in Orange County and the 10th most populous city in California. Anaheim is the second largest city in Orange County in terms of land area (after Irvine) and is known for its theme parks, sports teams, and convention center.

Anaheim was founded by fifty German families in 1857 and incorporated as the second city in Los Angeles County on March 18, 1876. The city developed into an industrial center, producing electronics, aircraft parts and canned fruit. It is the site of the Disneyland Resort, a world-famous grouping of theme parks and hotels which opened in 1955, Angel Stadium of Anaheim, Honda Center and the Anaheim Convention Center.

Anaheim's city limits extend from Cypress in the west to the Riverside County line in the east and encompass a diverse collection of neighborhoods and communities. Anaheim Hills is a master-planned community located in the city's eastern stretches that is home to many sports stars and executives. Downtown Anaheim has three mixed-use historic districts, the largest of which is the Anaheim Colony. The Anaheim Resort, a commercial district, includes Disneyland, Disney California Adventure, and numerous hotels and retail complexes. The Platinum Triangle, a neo-urban redevelopment district surrounding Angel Stadium, is planned to be populated with mixed-use streets and high-rises. Finally, Anaheim Canyon is an industrial district north of SR 91 and east of SR 57.

California

California (ⁱ/ˌkælᵻˈfɔːrnjə/ KAL-ə-FORN-yə, /ˌkælᵻˈfɔːrniə/ KAL-ə-FAWR-nee-ə) is a state located on the West Coast of the United States. It is the most populous U.S. state, with 39 million people, and the third largest state by area (after Alaska and Texas). California is bordered by Oregon to the north, Nevada to the east, Arizona to the southeast, and the Mexican state of Baja California to the south. It contains the nation's second most populous census statistical area (Greater Los Angeles Area) and the fifth most populous (San Francisco Bay Area), and eight of the nation's 50 most populated cities (Los Angeles, San Diego, San Jose, San Francisco, Fresno, Sacramento, Long Beach, and Oakland). Sacramento has been the state capital since 1854.

What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries. It was then claimed by the Spanish Empire as part of Alta California in the larger territory of New Spain. Alta California became a part of Mexico in 1821 following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The western portion of Alta California was organized as the State of California, which was admitted as the 31st state on September 9, 1850. The California Gold Rush starting in 1848 led to dramatic social and demographic change, with large-scale immigration from the east and abroad with an accompanying economic boom.

Angel Stadium

Angel Stadium of Anaheim, originally Anaheim Stadium and later Edison International Field of Anaheim, is a modern-style ballpark located in Anaheim, California, United States. Since it opened in 1966 it has served as the home ballpark of the Los Angeles Angels of Anaheim of Major League Baseball, and was also home to the Los Angeles Rams of the National Football League (NFL) from 1980 to 1994. The stadium is often referred to by its unofficial nickname The Big A. It is the fourth-oldest active Major League Baseball stadium, behind Fenway Park, Wrigley Field, and Dodger Stadium. It hosted the 1967, 1989, and 2010 Major League Baseball All-Star Games.

Angel Stadium and its surrounding parking lot are roughly bounded by Katella Avenue to the north, the Orange Freeway to the east, Orangewood Avenue to the south, and State College Boulevard to the west. Located near the eastern boundary of the parking lot is the landmark "Big A" sign and electronic marquee, which originally served as a scoreboard support. The halo located near the top of the 230' tall, 210-ton sign is illuminated following games in which the Angels win (both at home and on the road), which gives rise to the fan expression, "Light up the Halo!"

Triangle

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted .

In Euclidean geometry any three points, when non-collinear, determine a unique triangle and a unique plane (i.e. a two-dimensional Euclidean space). This article is about triangles in Euclidean geometry except where otherwise noted.
